Multiseptate gallbladder in a child with recurrent abdominal pain

WOS: 000285038500011PubMed ID: 19838987Multiseptate gallbladder, a rare congenital anomaly, can present with recurrent abdominal pain. Ultrasonography is the preferred imaging technique in patients with abdominal pain, especially for the evaluation of the gallbladder. We present the sonographic appearance of a multiseptate gallbladder

Carotid CT angiography: comparison of image quality for left versus right arm injections

WOS: 000294197400002PubMed ID: 20698005PURPOSE To evaluate the differences in image quality of carotid computed tomographic angiography (CTA) of patients injected with contrast material in their right arms versus patients injected with contrast material in their left arms. MATERIALS AND METHODS Patients who had cerebrovascular accidents and subsequently underwent CTA were included in the study. Contrast material was injected into the right arms of 44 patients and into the left arms of 46 patients. Source images of a total of 90 CTAs were retrospectively evaluated for perivenous streak artifacts and contrast material reflux into the veins of the neck and upper thorax. After adjusting for differences in gender, the relationship between the injection site and the intensity of perivenous streak artifacts and venous reflux was determined. RESULTS Perivenous streak artifacts and venous reflux were demonstrated in patients who underwent either right or left arm injections. However, the intensity of perivenous streak artifacts was stronger in patients who were injected with contrast material in the left arm. Venous reflux into the neck and upper thorax veins was also more severe and more frequent with left arm injections. A decreased retrosternal distance facilitated reversed flow into the veins when the left arm injection was used. CONCLUSION Perivenous beam hardening streak artifacts and venous reflux could not be prevented with right or left arm injections. However, patients who were injected with contrast material in their right arms showed fewer artifacts, thus allowing for better quality images on CTA

A rare case of granulomatous prostatitis caused by Mycobacterium tuberculosis

WOS: 000243573700012PubMed ID: 17024674We report a rare case of infective granulomatous prostatitis caused by Mycobacterium tuberculosis that may be mistaken for prostatic carcinoma, both on clinical examination and transrectal sonography (TRUS). A large hypoechoic mass was detected in the prostate of a 46-year-old man during TRUS and histopathologic examination after TRUS-guided biopsies reported the diagnosis of tuberculous prostatitis. We herein describe the clinical and TRUS findings of this case. (c) 2006 Wiley Periodicals, Inc

Role of contrast-enhanced 3D magnetic resonance portography in evaluating portal venous system compared with color Doppler ultrasonography

WOS: 000251821100017PubMed ID: 17440768Aim: The purpose of this study was to evaluate the capability of contrast-enhanced three-dimensional (3D) MR portography in detecting abnormal findings associated with the portal venous system compared with the results of color Doppler ultrasonography (CDUS). Materials and methods: MR portography findings were retrospectively compared with the results of CDUS examinations in 161 patients, who were suspected of having portal venous system abnormalities. Portal venous vessels were divided into main 5 groups including the main portal vein, its left and right intrahepatic branches, splenic vein and superior mesenteric vein. Imaging findings were classified as normal, occluded, or partially thrombosed. Results of clinical and imaging follow-up examinations including CDUS, MR portography or angiography, if available, were used as a proof of final diagnosis. The potential sites of varicose veins and collateral vessels were also examined by both imaging methods. Results: Vascular abnormalities were identified in 79 of 161 patients. There was a statistically significant agreement between the results of MR portography and CDUS in evaluating portal venous system (kappa = 0.871, P < 0.05). The sensitivity of MR portography was slightly superior to CDUS in detecting partially thrombosis and occlusion in the main portal venous vessels. In addition, MR portograms were superior to CDUS in the management of patients with portal hypertension by identifying portosystemic collaterals more adequately, and clearly demonstrated portal venous vessels that cannot be visualized at CDUS. Conclusion: Results of present study indicates that contrast-enhanced 3D MR portography is well suited and superior to CDUS in the management of patients with portal hypertension

Vascular complications after liver transplantation: evaluation with Doppler US

WOS: 000248108500013PubMed ID: 16967253Purpose: To demonstrate the spectral and color Doppler ultrasonography (US) findings that would indicate vascular complications after liver transplantation and to report our single center results of vascular complications detected in liver transplant recipients. Materials and methods: Our study was consisted of 326 patients who underwent liver transplantation procedures between November 1997 and May 2004. The records of all patients were reviewed retrospectively for the details of each patient's post-transplant Doppler US examinations, visceral angiographic examinations, and/or surgical procedures. Doppler US findings were correlated with angiographic results or surgery. Sensitivity and specificity of Doppler US parameters for the diagnosis of vascular complications of the hepatic artery, portal vein, and hepatic veins were calculated. Results: Vascular complications occurred in 47 patients (14%). Eight instances of vascular complications were detected intraoperatively by Doppler US at the time of transplantation. For hepatic artery complications, use of a Doppler US criteria resulted in a sensitivity and a specificity of 92% and 97%, respectively. Doppler US parameters also resulted in a sensitivity and a specificity of 100% in detecting portal vein complications, and resulted in a sensitivity of 99% and a specificity of 100% in detecting hepatic vein complications. Conclusion: Although it is clear that Doppler US evaluation is an effective choice for diagnosing vascular complications after liver transplantation, we also observed that Doppler US examination plays an important role in detecting vascular complications intraoperatively and improving the patient's chance for a successful outcome
