Functional evaluation of the urinary tract by duplex Doppler ultrasonography in patients with acute renal colic

Purpose: To determine the role of duplex Doppler ultrasonography (DDU) in Patients with acute unilateral renal obstruction. Subjects And Methods:A total of 161 Patients with suspected renal colic due to urolithiasis were evaluated by DDU followed by intravenous urography (IVU). The mean intra-arterial resistive index (RI) and the difference of mean resistive index between both kidneys (delta RI) were determined for each person. An RI value of ≥0.70 and a delta RI value of ≥0.06 were taken as the discriminatory threshold for obstruction. IVU results were considered the reference standard against which renal DDU findings were compared. Results: IVU showed both kidneys to be normal in 51 Patients and with unilateral ureteric obstruction in 110 Patients. The mean RI for obstructed kidneys was 0.67 (0.048), which was significantly higher (P-value Conclusion: Delta RI is more sensitive and specific than RI in acute renal obstruction. However, due to relatively low sensitivity for detection of partial obstruction, DDU cannot replace IVU as the standard imaging technique

METRONIDAZOLE ASSOCIATED SIDE EFFECT IN CEREBELLUM: A CASE REPORT

We interpret a case, manifesting Magnetic Resonance (MR) imaging features in relation with Metronidazole (Flagyl) toxicity. MRI brain exhibited an abnormal signal intensity comprising symmetrically bilateral dentate nuclei of cerebellum. The metronidazole toxicity was identified on MR imaging characteristics and reinforced on a clinical basis. In the hospital, metronidazole was stop. Patient recovered clinically with cessation of metronidazole. Follow-up MR imaging was not performed. In this report, we present a case establishing a characteristic finding in MR images within the dentate nuclei of cerebellum. Patient was treated for liver abscess and presented with slurring of speech, generalized weakness, and dysarthia

Diagnostic accuracy of contrast enhanced MRI pelvis in differentiating indeterminate adnexal lesions into benign and malignant with histopathological correlation

Background: The objective of our study was to determine the diagnostic accuracy of contrast-enhanced magnetic resonance imaging pelvis in differentiating indeterminate adnexal lesions into benign and malignant, while considering histopathological examinations as the gold standard.Methods: A total 880 patients who underwent contrast enhanced MRI pelvis in our institute from January 2014 to June 2016 were prospectively analyzed.Results: A total of 880 women were included in this study, of which 782 (88.8%) were younger than 50 years and 98 (11.1%) were older than 50 years. Mean patient age was 56.7 years and mean tumor size was 4.38 cm. There were 648 (73.60%) patients who had a tumor size of >4 cm, and 337 (38.29%) of these tumors were found to be malignant. Furthermore, tumors smaller than 4 cm in size were observed in 232 (26.36%) of patients, of which tumors in 225 (25.56%) patients were benign.Conclusions: The diagnostic accuracy of contrast-enhanced MRI was found to be significantly high (79.65%) in differentiating indeterminate adnexal lesions into benign and malignant lesions

Ultrasound Characterization Of Benign Breast Masses: A Review

A lump in the breast in any age group of women leads to the great anxiety. High frequency, high-resolution USG helps in its evaluation. However, it could be difficult to distinguish all benign from all malignant solid breast masses using USG criteria. Short-interval follow-up can be suggested. Ultrasound breast can also identified unsuspected occult masses in mammographicaly heterogeneous parenchyma breast. Various studies in past had discussed differentiating features b/w benign and malignant breast lesion. The American College of Radiology classified the breast masses in BIRADS-US classification. An exploration of literature search was determined utilizing the electronic databases of Pub Med, Google scholar, Elsevier from 200 to 2016 for English-language articles. The search terms utilized were breast masses. The titles and abstract of articles were evaluated Entire text and reviews were appraised when the abstracts meet to the inclusion criterion. This review included all articles that were used for the advancement of information about breast masses. Key Words: Breast ultrasound, Breast mass, ACR BIRADS-US criteri

An RI value of ≥0.70 and a delta RI value of ≥0.06 were taken as the discriminatory threshold for obstruction. IVU results were considered the reference standard against which renal DDU findings were compared. Results: IVU showed both kidneys to be normal in 51 patients and with unilateral ureteric obstruction in 110 patients. The mean RI for obstructed kidneys was 0.67 (0.048), which was significantly higher (P-value \u3c0.05) than a mean RI of contralateral normal kidneys 0.59 (0.04). The mean delta RI in patients with unilateral ureteric obstruction was significantly higher than that in patients with normal kidneys, at 0.076 (0.03) and 0.03 (0.05), respectively. In patients with complete obstruction, sensitivity of RI and delta RI were 77.5% and 92.5% with a specificity of 84.3% and 90.1%, respectively. In patients with partial obstruction, the sensitivity of these values was 22.8% and 62.8% with a specificity of 84.3% and 90.1%. Conclusion: Delta RI is more sensitive and specific than RI in acute renal obstruction. However, due to relatively low sensitivity for detection of partial obstruction, DDU cannot replace IVU as the standard imaging technique. © 2012 Sayani et al
