Defining anatomic variants of the coronary artery in taiwanese subjects using 64-multidetector-row computed tomography.

The newly developed 64-multidetector-row computed tomography (MDCT) prompted us to evaluate coronary angiography using this noninvasive method. We reviewed 281 images of MDCT coronary angiography in Taiwanese. The origins of the coronary arteries were identified from the luminal aspect of the aorta.

Prophylactic trans-uterine embolization to reduce intraoperative blood loss for placenta percreta invading the urinary bladder.

Reported herein is the case of a 35-year-old multipara woman diagnosed (on sonography) with total placenta previa that had ruptured through the myometrium of the uterus, invading the wall of the urinary bladder. In the 32nd week of gestation the patient underwent an emergency cesarean section due to profuse vaginal bleeding. Due to possible intraoperative massive bleeding during removal of the placenta it was decided to preserve the uterus and placenta temporarily.

Identification of a coronary-to-bronchial-artery communication with MDCT shows the diagnostic potential of this new technology: case report and review.

Development and refinement of multidetector computed tomography (MDCT) has brought the potential to replace conventional coronary angiography with a noninvasive technique that has comparable spatial and temporal resolution with a single breath-hold. Although clinical use of MDCT has largely been confined to evaluation of atherosclerotic coronary artery burden and coronary artery anomalies, it can be applied to diagnosis of other problems concerning the thoracic vasculature. We present the case of a middle-aged man who presented with recent-onset exertional angina: 64-detector CT was used as an alternative to cardiac catheterization and identified the underlying anatomic anomaly, a rare coronary-to-bronchial-artery communication.

Evaluation of the effect of partial splenic embolization on platelet values for liver cirrhosis patients with thrombocytopenia.

Aim: To investigate the effect of partial splenic embolization (PSE) on platelet values in liver cirrhosis patients with thrombocytopenia and to determine the effective embolization area for platelet values improvement.

Methods: Blood parameters and liver function indicators were measured on 10 liver cirrhosis patients (6 in Child-Pugh grade A and 4 in grade B) with thrombocytopenia (platelet values < 80 x 10(3)/microL) before embolization. Computed tomography scan was also needed in advance to acquire the splenic baseline.

Hyperintense putaminal rim sign is not a hallmark of multiple system atrophy at 3T.

Background And Purpose: Hyperintense putaminal rim (HPR) on the T2-weighted imaging, which has been observed in our daily practice while reading 3T brain images, has been described as a finding typical of multiple system atrophy (MSA). We hypothesized that the HPR sign is not an exclusive hallmark of MSA at a high magnetic field strength, but rather may be a normal finding.

Methods: Ten consecutive clinically healthy age-matched adults who showed recognizable HPR at 3T were subsequently examined on a 1.
