Goal: The aim of the study is to define the MRI appearance of disorder in the Junctional zone (JZ) in women with adenomyosis compared to those without it, given the importance of the JZ in the regulation of various reproductive events. Materials and methods: This was a prospective, comparative and open study. Patients with adenomyosis have been sorted in target group, n = 82, while the control group consisted of patients without adenomyosis, n = 82. All patients, from both groups have undergone a magnetic resonance imaging of the pelvis. Using a software tool for measurement, the thickness of the JZ was measured in T2w sag sequences in all patients from both groups (target and control) n = 164. Patients in the target group type adenomyosis were assessed and categorized either as: diffuse, focal, or Adenomyoma and the results were compared. The presence of endometriosis and myomas in both groups was evaluated and its coexistence with adenomyosis was analyzed as well. Results: Of the 82 patients in the target group, 81.7% of the patients had diffuse adenomyosis, while 18.3% had focal type with statistically significant difference (p <0.05). The results of the Mann-Whitney U test showed that p <0.05, implying that there is a statistically significant difference in the thickness of the JZ between the control and target group, therefore patients from the target group with adenomyosis had a statistically significantly thicker junctional zone than the patients in the control group. The JZ in the target group was on average M = 14,3mm, SD = 1.3mm, while the thickness of JZ in the control group without adenomyosis was M = 5,6mm, SD = 1,3. Chi-square shows that p <0.05, implying that there is a statistically significant difference in the number of patients with myomas between the two groups, where the myomas significantly over-represented in the target group with 32,9 % vs.6 %). Conclusion: MRI is the method of choice for imaging and evaluation of JZ as an important diagnostic marker in the diagnosis of adenomyosis. It is important to recognize this condition as early as possible and distinguish it from other pathologies in order for timely and appropriate treatment.

Liver injuries caused by high voltage electricity are rare and result in high mortality and morbidity. They are produced by the resistance to the passage of electrical current through the tissue, which creates heat that leads to coagulation necrosis and rupture of the cell membrane. We present a case of an electrical injury to the liver, diagnosed by ultrasound and CT in a 39-year-old man who presented with skin burns on his right hand and right hemiabdomen. Injuries occurred after the contact with 220 kV high voltage electricity.

Objectives: The aim of this study was to determine sensitivity, specificity, and predictive values of sonographically demonstrated ureteral dilatation in detecting vesicoureteral reflux (VUR). Methods: Ethical approval from the Ethical Committee of Clinical Center University of Sarajevo and parental consent were obtained for this prospective study involving 120 children with history of urinary tract infections (UTIs). Ultrasound examination included the evaluation of the urinary tract, with a special emphasis on evaluation of ureteral dilatation. Voiding urosonography (VUS) was carried out according to a standard protocol with the use of ultrasound contrast agent Sono Vue of second generation. Ureteral diameter greater than 3 mm was considered pathological. Proven VUR was graded into one of three stages. Results: Infectio tracti urinarii recidivans was referral diagnosis in the majority of patients. The average age of patients was 4.33 ± 3.88 years (from 2 months to 16 years of age). VUS findings were normal in 59 (49.2%), and pathological in 61 (50.8%) patients. Statistical analysis showed significant correlation between type and grade of VUR. Our data confirmed predominance of VUR in females and in children under the age of 5. Statistically significant correlation between ureteral dilatation and the existence of VUR was found, with relatively high sensitivity (67.2%), specificity (81.4%), and high positive (78.8%) and negative predictive value (70.6%), total diagnostic accuracy of 74.2% in detecting VUR, and significantly increased probability (20 – 25%) of detecting VUR in patients with sonographically confirmed ureteral dilatation. Conclusion: Sonographically confirmed ureteral dilatation can be used as a predictor of VUR in children with UTIs, and in combination with other predictors, might find a place in an evidence-based selective strategy in children with suspected VUR.

AIM To evaluate possibilities of computed tomography (CT) perfusion in differentiation of solitary focal liver lesions based on their characteristic vascularization through perfusion parameters analysis. METHODS Prospective study was conducted on 50 patients in the period 2009-2012. Patients were divided in two groups: benign and malignant lesions. The following CT perfusion parameters were analyzed: blood flow (BF), blood volume (BV), mean transit time (MTT), capillary permeability surface area product (PS), hepatic arterial fraction (HAF), and impulse residual function (IRF). During the study another perfusion parameter was analyzed: hepatic perfusion index (HPI). All patients were examined on Multidetector 64-slice CT machine (GE) with application of perfusion protocol for liver with i.v. administration of contrast agent. RESULTS In both groups an increase of vascularization and arterial blood flow was noticed, but there was no significant statistical difference between any of 6 analyzed parameters. Hepatic perfusion index values were increased in all lesions in comparison with normal liver parenchyma. CONCLUSION Computed tomography perfusion in our study did not allow differentiation of benign and malignant liver lesions based on analysis of functional perfusion parameters. Hepatic perfusion index should be investigated in further studies as a parameter for detection of possible presence of micro-metastases in visually homogeneous liver in cases with no lesions found during standard CT protocol.

AIM To analyze the usefulness of five ultrasound parameters (ureteral dilatation, renal pelvis dilatation, renal parenchyma width reduction, calyceal dilatation, and urothelial reaction) in detecting vesicoureteral reflux (VUR). METHODS The study included 101 patients with diagnosed and therapeutically treated urinary infection. The ultrasound examination and voiding urosonography (VUS) were carried out according to a standard protocol. In the group of patients with proven VUR the presence of the indirect ecomorphological signs of VUR was evaluated. RESULTS The referral diagnosis urinary tract infection was present at the admission in 53 patients, while the remaining 48 patients were admitted with the diagnosis of infectio tractus urinarii recidivans. Pathological VUS was found in 53 patients. The ultrasound parameter with the highest sensitivity, specificity, and negative predictive value (77.4%, 79.2%, and 76.0%, respectively) in detection of VUR was urethral dilatation, while the parameter with the highest positive predictive value (62.5%) in detection of VUR was urothelial reaction. CONCLUSION In case of ultrasound verification of ureteral dilatation or urothelial reaction, especially in if the urinary infection has proved, it is necessary to exclude the existence of VUR.

BACKGROUND Renal artery aneurysm is very rare and most often incidental finding and we will present it in our case report. CASE REPORT We report a case of 65 years old women who was sent to our hospital Clinic of Radiology. We detected a renal artery aneurysm on the left side on the ultrasound and later we confirmed it on the CTA of the abdominal aorta and its visceral branches. DISCUSSION Renal artery aneurysms can be classified in true anaurysm and pseudoaneurysm. They are more often find at females. They can be fusiform or saccular in appearance and are extraparenchymal in 90% of cases. Most are saccular and noncalcified. CONCLUSION In the case of renal artery aneurysm that we founded we recommended regular Color Doppler ultrasound examinations, consultation from the urologist and CTA control if there is a need.

Ultrasound device, essentially, consists of a transducer, transmitter pulse generator, compensating amplifiers, the control unit for focusing, digital processors and systems for display. It is used in cases of: abdominal, cardiac, maternity, gynecological, urological and cerebrovascular examination, breast examination, and small pieces of tissue as well as in pediatric and operational review.

Ultrasound devices and methodologies have been continuously evolving and becoming more important as tools in diagnostic medicine. Recently a new ultrasound diagnostic technique has been developed. Named sonoelastography, the technique enables evaluation of tissue elasticity and is based on differences in stiffness (hardness, compressibility, elasticity) of pathological changes and normal adjacent tissue. Sonoelastography (SE) is also known as Real-time tissue elastography (RTE), Real-time sonoelastography (RTSE), Tissue type imaging (TTI) and Ultrasound Strain Imaging Technology. It has been found useful in many medicine � elds and adopted readily by clinicians of different specialties. It gives more information than conventional ultrasound in evaluation of tumors, liver disease, skeletal muscles, rheumatoid nodules and other pathological changes. This review covers the basics of elastography, its applications, instruments, techniques, the scoring system and the indications for elastography. © 2011 University of Sarajevo Faculty of Health Studies
