BACKGROUND Whether an intervendor discordance of myocardial velocities determined by tissue Doppler echocardiography (TDE) can be generalized remains unclear. We compared intervendor variabilities of left ventricular (LV) and right ventricular (RV) myocardial velocities among three TDE systems. METHODS Examinations with TDE were performed in 41 healthy(More)
The usefulness of sulfamethizole capsulescontaining contrast medium in gastric emptying tests forfunctional dyspepsia was evaluated in five healthyvolunteers and nine patients with dysmotility-likesymptoms. Each subject swallowed 15 capsules with aliquid, food, and at 0, 15, 30, 45, 60, 90, and 120 min,the capsule position and size were(More)
BACKGROUND Inter-vendor discordance in three-dimensional speckle-tracking echocardiography (3DS) remains uncharacterized. We aimed to examine inter-vendor discordance of left ventricular (LV) volumes, and functional parameters and their reproducibilities between two commercially available 3DS systems. METHODS Echocardiographic examinations with 3DS were(More)
BACKGROUND Deep vein thrombosis (DVT) develops after major orthopedic surgery despite the current use of prophylaxis. DVT frequently develops in the soleal vein (SV) and might develop easily at the site of SV dilatation because of blood flow stasis. However, whether preoperative SV dilatation detected by ultrasonography predicts DVT after major orthopedic(More)
BACKGROUND Pulmonary hypertension (PH) is a strong predictor of mortality in patients with interstitial lung disease (ILD). However, patients with ILD often have poor outcomes even in the absence of PH. Pulmonary vascular resistance (PVR) assessed by right heart catheterization is a predictor of mortality in patients with ILD. However, the clinical utility(More)
