The purpose of the study was to compare the results of the analysis of residue or recurrence of the aneurysm after endovascular treatment using 3D RA and 2D digital subtraction. Method. In 68 patients with 76 cerebral aneurysms, we made regular controls using both techniques, 2D DSA and 3D RA. Residual and recurrent aneurysms are classified into five stages, and the pictures taken by both modalities are compared. Results. 2D DSA detected the residual and recurrent aneurysm in 53.70% of cases (29/54 aneurysms), and 3D RA in 66.67% (36/54 aneurysms). In nine cases in 2D DSA did not detected residues of which was discovered in 3D RA, and 3 cases of 2D DSA reveals little short neck aneurysm, which is on the 3D RA, in fact, a small aneurysm. In five cases from the use of 3D RA reduced the level of classification aneurysm. Conclusion: 3D RA reveals more residues aneurysms.

The study was conducted at the Clinic of Radiology and Nuclear Medicine at Tuzla University Clinical Center, in the period from June to October 2018. The study was carried out in 2 phases: in the first phase, the standard protocol for the region of the body being recorded was used, and in the second phase CT examinations were performed according to the modified protocol (by changing the parameters of the mAs and kV values), with the minimum requirements regarding image quality. Based on dosimetry indicators, the effective dose and radiation risk for patients in both phases was assessed. The image quality for each patient was evaluated using a three-stage visualization scale for each parameter of the anatomical region. The total number of patients involved in the study was 312. The results showed that with optimum protocol selection in terms of exposure parameters (by increasing and decreasing the value of mAs and kV), it is possible to significantly decrease the dose of radiation in the head examination by 5%, in the chest examination by 2%, in the chest and upper abdomen examination by 6%, and when examining the abdomen by 8%. By applying standard imaging protocols, the quality of image necessary for adequate radiological interpretation is achieved, hence a higher radiation dose than necessary. With optimum protocol selection in terms of exposure parameters, it is possible to significantly reduce the dose of radiation, with a satisfactory quality of the diagnostic image necessary for further radiological interpretation.

These meningiomas are characterized by an invasive growth pattern with extensive skull base infi ltra-skull base infi ltra-skull base infiltration in all directions and by the mixed permeative-sclerotic appearance of the bone margins of the jugular foramen. We report an unusual case of a primary jugular foramen meningioma in a 30-year-old woman. The unenhanced highresolution CT of the temporal bones revealed extensive bone destruction around the left jugular foramen as well as bone destruction of the basilar part of the left occipital bone without sclerosis. These findings are unusual for meningiomas and correspond more to glomus jugulare tumors. In the literature, we did not find a case similar to ours. Conclusion. MRI and CT imaging provide accurate distinction between meningioma and glomus tumors or schwannomas in most cases. From high-resolution CT scans, in the case where a permeative-destructive pattern is dominant, and with the absence of hyperostosis and bone thickening around the jugular foramen, the differential diagnosis between jugular foramen meningiomas and other tumors, especially glomus jugulare tumors, is difficult. In that case the correct diagnosis should be based on the MRI findings.

Endovascular embolization was performed in thirty-two patients with cerebral AVMs. The objective of endovascular AVM treatment is set for each patient upon consultations with a radiologist and a neurosurgeon. In most cases, the disorder is asymptomatic. We report our initial experiences in the treatment of brain AVMs with Onyx embolization. Methods Between January 2015 and December 2015, 32 patients with brain AVMs were embolized with Onyx. Clinical presentation included incidental finding in 2 patients, neurologic deficits in 1 patient, headaches in 7 patients, seizures in 9 patients and intracerebral haemorrhage in 12 patients. According to the Spetzler-Martin scale, one AVMs was grade I, 5 were grade II, 17 were grade III, 7 were grade IV, and 2 were grade V. Twenty-eight (86%) AVMs were located in eloquent regions. Initial complete obliteration after final embolization was achieved in 7 patients (20.2%), with an average of 85.5% (range, 30-100%) volume reduction. One-year follow-up angiography was performed on 11 (34.8%) patients. Conclusions Endovascular treatment of cerebral AVMs with super selective embolization with ONYX is a safe and effective alternative treatment paths next to microsurgery.

This report presents a patient with signs of subclavian steal syndrome (SSS) caused by a thrombus in the initial part of the right subclavian artery. Pathological occlusive changes, such as thrombosis, are four times more common on the left subclavian. Thrombosis of the subclavian artery occurs in about 1% of the population, but atherosclerotic changes are common and usually asymptomatic. Objective: The aim of this report is to present a patient with signs of subclavian steal syndrome (SSS) caused by a thrombus in the initial part of the right subclavian artery associated with symptoms of COVID-19. Case report: A 56-year-old female patient presented with tremor, numbness and prickling in the right hand, tinnitus, blurred vision, vertigo, syncope, trismus and headaches. The formation of a thrombus caused neurological symptoms in the right hand with a stronger pronounced tremor, headache and syncopal e...

COVID-19 affects all organs and organ systems. The symptoms of the affected organs can last for a long time after the acute infection. About 1/3 of patients develop neuropsychiatric signs in the clinical course of the disease. The most common symptoms are mental fog, headache, cognitive changes, behavior changes, muscle weakness, anosmia and ageusia. These symptoms may develop due to a direct effect of the virus on the neurons or hyper reactive immune response. Objective: The aim of this article is to describe 2 young adults who developed neuropsychiatric symptoms in the course of Long COVID-19 syndrome. Ischemic vasculitis was proved using CT imaging. Case report: We collected data of two younger females who had previously recovered from the acute form of COVID-19 without respiratory complications. They developed in the next 1-2 months a clinical picture of a brain disorder. In both cases, CT and angiography scans of the brain showed signs of ischemic vasculitis. Neurological therapy has led to an improvement of the neuropsychiatric symptoms. Conclusion: Neuropsychiatric disorders in Long Covid syndrome are common and diverse. Two cases of young adults who developed signs of neurological disorder in the post COVID-19 period were presented, and CT scans of the brain showed signs of ischemic vasculitis.

In this paper we propose an automatic method for lung segmentation with previous preprocessing of the lung computed tomography images. Our algorithm starts with segmentation with the initial thresholding to create binary image. After creation of the binary image, the threshold is used to set all the pixels under the selected value to the background. This will eliminate the table and other non anatomical pixels from the images. The algorithm is looking for the first pixel on the CT image, and after it is found, the region growing commence, and the lung region is segmented containing right and left lung and airway. Morphological operators are used to enhance the image edges, as well to include the missing tissue due to their high attenuation. The results were compared with the volume found by human observer’s segmentation, and for measure of similarity we used Pearson correlation coefficient, and with the P=0.9...

Materials and methods: Seventy-seven patients with AVMs were examined by using a digital subtraction angiographic (DSA) and computerised tomographic (CT) examination, including three-dimensional reconstruction of the brain vessels. In addition, the arteries of 4 human brain stems and 8 cerebral hemispheres were microdissected. Results: The anatomic examination showed a sporadic hypoplasia, hyperplasia, early bifurcation and duplication of certain cerebral arteries. The perforating arteries varied from 1 to 8 in number. The features of the leptomeningeal and choroidal vessels were presented. The radiologic examination revealed singular (22.08%), double (32.48%) or multiple primary feeding arteries (45.45%), which were dilated and elongated in 58.44% of the patients. The feeders most often originated from the middle cerebral artery (MCA; (23.38%), less frequently from the anterior cerebral artery (ACA; 12.99%), and the posterior cerebral artery (PCA; 10.39%). Multiple feeders commonly originated from the ACA and MCA (11.69%), the MCA and PCA (10.39%), the ACA and PCA (7.79%), and the ACA, MCA and PCA (5.19%). The infratentorial feeders were found in 9.1% of the AVMs. Contribution from the middle meningeal and occipital arteries was seen in 3.9% angiograms. Two cerebral arteries had a saccular aneurysm. The AVM haemorrhage appeared in 63.6% of patients. Conclusions: The knowledge of the origin and anatomic features of the AVMs feeders is important in the explanation of neurologic signs, and in a decision regarding the endovascular embolisation, neurosurgical and radiosurgical treatments.

The aim of this study was to determine the prevalence of symmetry, asymmetry and hypoplasia of the intracranial internal carotid artery (ICA), and the possible presence of other variants of the ICA by magnetic resonance angiography (MRA). Subjects and methods. This prospective-retrospective study included 1000 subjects who underwent consecutively MRA of the cerebral arteries. 3D-time of flight angiograms were performed according to the standard protocol. We measured the diameter of the ICA and the diameter of the A1 segment of the anterior cerebral artery (ACA). The symmetry, asymmetry and hypoplasia of the ICA, as well hypoplasia of the A1 segment of the ACA were analysed using the vascular asymmetry coefficient. Results. The right and left ICA were symmetrical in 93.9% examinees, and asymmetrical in 6%, while ICA hypoplasia was found in only one patient (0.1%). Other variants of the ICA were not found. There was no significant difference in the prevalence of individual variations between male and female patients, and no significant frequency difference was found between anatomical variations in terms of the right and left ICA. In 38.3% patients with asymmetrical ICAs, aplasia or hypoplasia of the A1 segment of the ACA was found on the side of the ICA with a reduced diameter. Conclusion. Congenital hypoplasia of ICAs is a very rare abnormality, while asymmetry of ICAs is more common. After evaluating severe asymmetry of intracranial ICAs by MRA, MRA of the neck is recommended, especially in patients with a complete anterior part of the circle of Willis.

A hydronephrotic kidney usually contains 1–2 litres of fluid in the collecting system. We report a case of a 24 year old man with a hydronephrotic left kidney, from which 14 litres of fluid was surgically drained. In this report the importance of computed tomography in the diagnosis and differential diagnosis of giant hydronephrosis to other cystic masses is emphasised. Conclusion. GH should be included in the differential diagnosis of huge intraabdominal cystic masses. CT alongside MR should be the method of choice.

WG relatively frequently affects the nervous system (in 30-50%), usually in the form of peripheral or cranial neuropathy. Involvement of the brain is reported in a very small percentage of patients (2%-8%). Three major mechanisms have been described as the cause of central nervous system (CNS) disease in WG: contiguous invasion of granuloma from extracranial sites, remote intracranial granuloma and CNS vasculitis. CNS involvement caused by contiguous invasion of granuloma from extracranial sites is the rarest. We report the case of a 37-year-old man with WG, manifested as a pulmonary and paranasal sinuses disease, with orbital and CNS involvement, caused by contiguous invasion from the paranasal sinuses. In this report, the rich spectrum of findings achieved by computed tomography and magnetic resonance are demo...

Dose-area-product (DAP) measured by the angiography system and computed-tomography dose index (CTDI) do not appear practical for dose assessment. Hence, we performed real dose measurements in anthropomorphic phantoms. Methods: Three different anthropomorphic phantoms (10 kg, 19 kg and 73 kg bodyweight) equipped with thermoluminescent dosimeters (TLD) were used. We used a typical standard diagnostic program and a low-dose program. The effective dose (ED) was calculated according to the International Commission on Radiological Protection (ICRP) 103. The 3D distribution of radiation in the body was assessed. Results: ED for the male 10 kg phantom was 0.192 mSv in the diagnostic program and 0.050 mSv (male) in the low-dose program. The 19 kg phantom received an ED of 0.205 mSv (male) in the diagnostic program. In the low-dose program the ED reached 0.058 mSv (male). The male adult 73 kg phantom was exposed with an ED of 0.730 mSv in the diagnostic program and 0.282 mSv in the low-dose program. ED for the female phantoms was slightly higher for both acquisition-programs. Dose distribution was inhomogeneous with a dose maximum in the esophageal region behind the heart, whereas in the brain, intestine and gonads we found nearly no radiation. Conclusions: 3D-RA imaging in the interventional catheter laboratory is possible with an effective dose lower than 1 mSv. With its potential to reduce fluoroscopic time and the number of control angiographies in catheterization and intervention in complex anatomy, it can decrease the radiation dose.
