Anatomic variations of the intrahepatic bile ducts: analysis of magnetic resonance cholangiopancreatography in 1011 consecutive patients.

Objectives: The aim of the study was to evaluate the frequency of anatomic variations of the hepatic duct bifurcation using magnetic resonance cholangiopancreatography (MRCP).

Methods: A total of 1,160 consecutive patients, referred to our department for MRCP due to suspected pancreatobiliary disease or before liver transplantation, were reviewed retrospectively. A total of 149 patients with less than optimal results due to imaging limitations or secondary differentiations of bile duct anatomy were excluded from the study.

The effect of radioiodine on the intima media thickness of the carotid artery.

Aim: The radiation can induce vessel injury. The result of this injury can be severe and life-threatening. There are a few studies demonstrating an increase in intima-media thickness (IMT) of the common carotid artery (CCA) after radiotherapy, especially in head and neck cancers.

An evaluation of thyrotoxic autoimmune thyroiditis patients with triplex Doppler ultrasonography.

Objective: This study aimed to investigate the usefulness of blood flow parameters obtained from STA and CCA with Triplex Doppler ultrasonography (TDU) on patients with thyrotoxicosis.

Materials And Methods: This cross-sectional study included consecutive 24 patients with thyrotoxicosis and 18 healthy controls. The thyroid gland blood flow parameters were evaluated with TDU.

The role of dynamic subtraction MRI in detection of hepatocellular carcinoma.

Purpose: The aim of this study was to investigate the role of dynamic subtraction magnetic resonance imaging (MRI) in detection of hepatocellular carcinoma (HCC) in patients with cirrhosis.

Materials And Methods: MR images of 32 patients with cirrhosis were retrospectively investigated. The standard sequence images of the patients were evaluated for detection of HCC, and then the subtracted images of dynamic contrast-enhanced series were evaluated.

The role of SPIO-enhanced MRI in the detection of malignant liver lesions.

The aim of this study was to evaluate the efficacy of superparamagnetic iron oxide (SPIO)-enhanced magnetic resonance imaging (MRI) in the detection of malignant liver tumors. MRI, using fast spin-echo T(2)-weighted and gradient-echo T(1)-weighted imagings before and after SPIO infusion, was performed in 32 patients with known or suspected hepatic lesions. Statistical analysis was performed using lesion-by-lesion analysis.

Echo contrast-enhanced power Doppler ultrasonography for assessment of angiogenesis in renal cell carcinoma.

Objective: Tumoral growth is an angiogenesis-dependent event. Although there are studies about the importance of histopathologic angiogenesis in various malignancies, the assessment of the angiogenesis by radiologic techniques is not well established. The aim of this study was to investigate the efficacy of echo contrast-enhanced power Doppler ultrasonography (PDUS) in determining the angiogenic status of renal cell carcinoma (RCC).

Ectopic spleen and left-sided vena cava in Beckwith-Wiedemann syndrome.

Beckwith-Wiedemann syndrome (BWS) is a congenital overgrowth syndrome characterized by anterior abdominal wall defects, macroglossia, and gigantism. A variety of other abnormalities have been described, however association with ectopic spleen and left-sided vena cava has not been reported previously. We report ectopic spleen, left-sided vena cava and the other abdominal imaging findings of an adult BWS case who came up to date without any follow-up from the early childhood.
