Abstract: The current study aim is the role of multi-slice CT perfusion in assessment of pulmonary nodules. Eighty patients with pulmonary nodules underwent non contrast CT scan of the chest and dynamic CT perfusion of the chest. Dynamic CT chest perfusion of 80 patients with pulmonary nodules revealed 24 patients had benign nodules of low biological activity, 16 patients had benign nodules of high biological activity and 40 patients had malignant nodules (16 of them had multiple nodules in both lung fields and clinical history of primary extra pulmonary malignancy, so diagnosed as metastatic nodules). Perfusion flow, extraction fraction and blood volume; these indexes showed significant differences between malignant nodules and benign nodules with low biologic activity (P>0.0001) In addition, these indexes showed a significant difference between benign nodules with high biologic activity and those with low biologic activity (P>0.0001) and the perfusion flow was of high benefit for nodules characterization than ejection fraction and blood volume by the higher significant values. CT perfusion compared the effect of therapy (chemotherapy and or radiotherapy) on metastatic pulmonary nodules before and after start of treatment by perfusion parameters (perfusion flow, extraction fraction and blood volume) & colour maps with the clinical data and follow up revealed that both results closely near and raise the efficacy of CT perfusion study in follow up and assessment of treatment response in metastatic pulmonary nodules. It can be concluded that CT perfusion is a feasible non-invasive diagnostic technique able to evaluate the nature of pulmonary nodules and treatment response in patients with metastatic pulmonary nodules.

Abstract: Objective: To evaluate the characteristics of ureteral jets in patients with ureteral stones by color Doppler ultrasonography. Method: 49 patients (patient group) with unilateral ureteral stones proved by non contrast spiral CT and another 40 healthy volunteers (control group) who have no any previous urinary complaint were examined for their ureteral jets by color Doppler ultrasonography for ureteral jet number per 5 minutes as well as its peak velocity (cm/s). Statistical analysis was done by using Social Sciences computer program (SPSS) version 17, p-values less than or equal to 0.05 were considered statistically significant difference. Results: There was a significant statistical difference between the healthy volunteers and the patients with ureteral stones (p < 0.001). However, there was no statistical difference between the healthy volunteers on both sides and also the healthy volunteers and the non – obstructed side of the patients with ureteral stones (p > 0.05). So the healthy side could be used as a reference to the diseased side according to our results. Conclusion: The color Doppler evaluation of the ureteral jets (its number and velocity) is a valid method of evaluating ureteral calcular obstruction and could be a first line of management to detected ureteric obstruction especially in patients with acute flank pain which may be controversial for other causes of acute abdomen in the emergency department.

Abstract: Introduction: Chronic rhinosinusitis (RSC) is a disabling disease that can affect up to 70% of people. It is very important to know which are the anatomical variants that the patient presents for surgical planning and often for the treatment of the variants that can present as a risk factor. The evidence shows heterogeneity in the prevalence of these anatomical variants and it is not described quantitatively which are the variants that present the greatest relationship as a risk factor. Establishing the multiparametric correlation between at least one of the most frequent anatomical variants of the paranasal sinuses and the development of rhinosinusitis is the most important objective of this investigation. Materials and methods: Case-control study with multiparametric correlation analysis of the anatomical variants of paranasal sinuses as a risk factor in the development of sinusitis. Analysis with measures of central tendency, Xi2, Fisher's exact test, binary logistic regression. Results: The most frequent anatomical variant was the deviation of the nasal septum on the left side (78%). The second most common variant found was the Agger Nasi cells (68%), followed by the protrusion of the Vidian nerve in the sphenoid sinus (52%). The only anatomical variant that could be determined within the regression model was the obstruction of the osteomeatal complex; which is presented as a risk factor with an OR of 16 (95% CI: 6.9-41.3). Conclusions: Obstruction of the osteomeatal complex is a very important risk factor for the development of chronic rhinosinusitis.

Abstract: Gallstone ileus is a rare cause of acute abdomen, representing less than 1% of intestinal obstruction. It is due to mechanical small bowel obstruction (SBO) by a migrated gallstone. we report this observation to illustrate the imaging findings especially in CT scan. A 62-year-old woman was admitted to emergency for acute bowel obstruction. The CT scan has confirmed jejunal bowel distension with fluid levels upstream endoluminal formation which was rounded and well limited, measuring 5 cm of long axis. This training was slightly hyperdense with hypodense areas of fat density. Moreover, there was aerobilia with multiple fistulas between the duodenum (D1) and gallbladder, which was empty. The triad of aerobilia, small bowel obstruction and migrant gallstone was suggestive of gallstone ileus diagnosis. The patient was operated with good evolution. Gallstone ileus is an uncommon presentation of gallstone disease. It is frequently observed in elderly patients with a history of cholelithiasis or cholecystitis. Early diagnosis is crucial and would avoid morbidity and mortality related to this disease. CT scan shows the classical triad of Rigler with pneumobilia, an ectopic stone and mechanical ileus. CT may improve the diagnosis providing important information regarding the exact number, size, and location of ectopic stones and the site of intestinal obstruction or direct visualization of a biliary–enteric fistula, to help clinicians in the therapeutic management of patients.
