OBJECTIVE This study was designed to compare the diagnostic performance of gadoxetic acid-enhanced magnetic resonance imaging (MRI) with gadobenate dimeglumine-enhanced MRI for preoperatively detecting hepatocellular carcinoma (HCC). MATERIALS AND METHODS Eighteen consecutive patients (17 men and one woman, age range: 31-73 years) with 22 HCCs underwent(More)
OBJECTIVE To retrospectively determine the optimal b value of diffusion-weighted imaging (DWI) for predicting the presence of localized prostate cancer, and to evaluate the utility of DWI under different b values in differentiating between cancers and benign prostatic tissues. MATERIALS AND METHODS Eighty patients with suspected prostate cancer underwent(More)
OBJECTIVE We investigated low dose digital tomosynthesis (DT) for the evaluation of the paranasal sinus (PNS), and compared its diagnostic accuracy with a PNS radiography series (XR). MATERIALS AND METHODS We enrolled 43 patients for whom XR, PNS DT, and OMU CT were performed. We measured effective doses (EDs) of XR, DT, and OMU CT using Monte Carlo(More)
To the editors, We read with great interest the article titled " Diffusion-This article will be a useful diffusion weighted imaging (DWI) guide for radiologists in assessing prostatic cancer. In the paper, the authors compared 4 different b values and suggested them for predicting prostate cancer; the optimal b value for 3T DWI was found to be 1000 s/mm 2.(More)
The meniscus root plays an essential role in maintaining the circumferential hoop tension and preventing meniscal displacement. Studies on meniscus root tears have investigated the relationship of osteoarthritis and an anterior cruciate ligament tear. However, few studies have directly compared the medial and lateral root tears. To assess the prevalence of(More)
