BACKGROUND Acoustic radiation force impulse (ARFI) is a new technology integrated into conventional B-mode ultrasonography. ARFI is used to evaluate tissue stiffness in several organs, but this method has not been applied for liver fibrosis. AIM The aim of this study was to determine whether ARFI elastography is useful for the evaluation of liver… (More)
Purpose: To clarify the immediate effect and long-term results of bronchial artery embolization (BAE) for hemoptysis due to benign diseases and the factors influencing the outcomes. Methods: One hundred and one patients (aged 34–89 years) received bronchial artery embolization with polyvinyl alcohol particles and gelatin sponge for massive or continuing… (More)
Sclerosing stromal tumor is a rare ovarian neoplasm. We describe the radiologic findings of sclerosing stromal tumor in two patients. In both patients, MR and CT images showed a large mass in the left adnexal region. On dynamic contrast-enhanced images, the tumors showed early peripheral enhancement with centripetal progression.
Two cases of extremely rare aneurysms of peripheral portions of the AICA are reported with a review of the pertinent literature. According to reported surgical findings, nearly all of the aneurysms originated from arterial loops near the internal acoustic meatus. These aneurysms can therefore, cause the cerebellopontine angle syndrome, with or without… (More)
PURPOSE The purpose of this study was to describe variations of the proximal segments of the superior cerebellar artery (SCA) detected by magnetic resonance (MR) angiography. MATERIALS AND METHODS We reviewed 145 consecutive MR angiograms. All patients were studied with a 1.5-Tesla imager using the three-dimensional time-of-flight technique. RESULTS… (More)
We report the MRI findings in two patients with cystic dilatation of the ventriculus terminalis. The latter is usually a tiny ependyma-lined cavity of the conus medullaris. In both cases the markedly dilated ventriculus terminalis was seen as a rounded cavity with regular margins, the content of which gave the same signal as cerebrospinal fluid with all MR… (More)
This is a report of two patients in whom a pontine venous congestion occurred with a dural carotid-cavernous fistula (CCF), an extremely rare complication. This is the first such report. We underscore the importance of early diagnosis and treatment of dural CCFs.
Persistent trigeminal artery (PTA) variants are cerebellar arteries that originate directly from the precavernous portion of the internal carotid artery (ICA). The goal of our study was to determine the incidence and MR angiographic features of PTA variants. Between April 1996 and September 1999, 523 cranial MR angiographies were performed at our… (More)
We investigated 7505 inpatients who underwent intravenous urography or contrast-enhanced computed tomography to assess risk factors for delayed adverse drug reactions to iohexol, a non-ionic iodinated contrast medium. Focusing on delayed adverse reactions, all adverse events were prospectively investigated for 7 days after injection of iohexol. To explore… (More)
