Skeletal involvement is the second most common site of metastases after lymph nodal metastases in patients with prostate cancer. The skeletal metastases from prostate cancer are osteoblastic in nature and show increased tracer avidity on the bone scan. Focal tracer avid lesion in skeleton especially in skull requires the careful examination by further investigation. The patients with skull meta...

BACKGROUND Imaging modalities (computed tomography (CT), ultrasonography, and magnetic resonance imaging (MRI)) have only limited ability to distinguish liver focal nodular hyperplasia (FNH) from metastatic liver tumors. Here, we report a patient who underwent surgery for benign FNH that mimicked a liver metastasis from soft tissue sarcoma (STS). CASE PRESENTATION A 23-year-old man with a his...

Gadobenate dimeglumine-enhanced magnetic resonance (MR) imaging simultaneously provides both morphological and functional information by the acquisition of dynamic and hepatobiliary-phase imaging. Focal lesions with no functioning hepatocytes, where hepatobiliary metabolism is blocked or inhibited, are generally unable to uptake and excrete gadobenate dimeglumine into the bile. Such lesions are...

Background and Aim: Focal liver lesions represent a gamut of benign malignant pathologies which are sometimes incidental. The primary mode investigating these is radiological workup, hence radiologist need to be thoroughly aware the varied imaging appearances focal lesions. must able categorize lesion as or with certain level diagnostic accuracy. Herein, we mainly try highlight atypical, often ...

OBJECTIVE Diffusion-weighted imaging (DWI) is usually performed before administration of intravenous contrast agents. Repetition of DWI is occasionally necessary after contrast administration, but the effects of contrast material on DWI and apparent diffusion coefficient (ADC) values in the abdomen have not yet been fully examined. The purpose of this work is to assess whether administration of...

A 73-year-old woman was incidentally found to have a hypervascular nodule in the liver (S5) with imaging. She was subsequently followed under a diagnosis of suspected hepatic hemangioma because of continued enhancement in portal venous phase CT scan (Fig. 1A). Liver function test and tumor marker were within normal limits. Both HBs antigen and HCV antibody were negative. She had no history of t...

BACKGROUND This study was conducted to investigate whether apparent diffusion coefficient (ADC) measurements by dividing the liver into left and right hepatic lobes may be utilized to improve the accuracy of differential diagnosis of benign and malignant focal liver lesions. MATERIALS AND METHODS A total of 269 consecutive patients with 429 focal liver lesions were examined by 3-T magnetic re...
