Background Three-dimensional myocardial perfusion MRI offers better myocardial coverage than conventionally used two-dimensional methods. bSSFP three-dimensional myocardial perfusion MRI at 3 Tesla potentially offers further improvement of signal characteristics and may enhance the use of three-dimensional myocardial perfusion MRI for clinical application. Methods Twenty-five healthy volunteers...

Background Perfusion imaging visualizes early changes within the ischaemic cascade and has been shown to accurately detect significant coronary artery stenoses. First pass myocardial perfusion CMR yields high spatial resolution and permits quantification of myocardial blood flow. However, perfusion-CMR has only been validated in a small number of previous studies and using relatively early perf...

High fat diet-induced glucose intolerance impairs myocardial function, but not myocardial perfusion during hyperemia: a pilot study 3 Myocardial function and perfusion during glucose intolerance 51 Abstract Introduction

Myocardial involvement in progressive muscular dystrophy of the Duchenne type was evaluated in 19 patients using thallium-201 myocardial perfusion imaging. A qualitative analysis was performed from five projection images by three experienced physicians. Distinct perfusion defects were shown in 13 patients, especially in the LV posterolateral or posterior wall (11 patients). There was no signifi...

BACKGROUND Artificial neural networks have successfully been applied for automated interpretation of myocardial perfusion images. So far the networks have used data from the myocardial perfusion images only. The purpose of this study was to investigate whether the automated interpretation of myocardial perfusion images with the use of artificial neural networks was improved if clinical data wer...

BACKGROUND Cardiac magnetic resonance (CMR) and [(11)C]acetate positron emission tomography (PET) were used to assess the hypothesis that patients with nonischemic dilated cardiomyopathy (NIDCM) have decreased subendocardial perfusion reserve and impaired oxidative metabolism, consistent with the concept of "energy starvation" in heart failure (HF). METHODS AND RESULTS CMR myocardial perfusio...

introduction: although left ventricular(lv) function parameters measured by gated myocardial perfusion spect (gspect) have been validated, experimental data have revealed that the calculated the lv function parameters using gspect are affected by patient populations as well as particular acquisition and processing conditions. we tried to determine the normal values of gspect in an iranian popul...

BACKGROUND The aim of the present study was to investigate the prognostic implication of myocardial perfusion in patients with ST-segment-elevation myocardial infarction (STEMI) and signs of heart failure, treated with primary angioplasty. METHODS AND RESULTS Our population is represented by 1548 consecutive patients undergoing primary angioplasty for STEMI. Congestive heart failure was defin...

To map precise myocardial perfusion anatomy, we correlated detailed coronary arteriographic anatomy for every coronary artery and all secondary branches in the heart that had flow-limiting stenosis with corresponding specific, circumscribed, myocardial perfusion defects by positron emission tomography. Eight hundred ninety-five patients with abnormal coronary arteriograms showing any visible co...

UNLABELLED This study was designed to assess the prognostic value of stress myocardial perfusion SPECT with electrocardiographic (ECG) gating in patients undergoing noncardiac surgical treatment. METHODS The study included 481 consecutive patients who underwent noncardiac surgery and had been referred for preoperative myocardial perfusion scintigraphy. Myocardial scintigraphy used (99m)Tc-lab...
