Background In patients with coronary artery disease, a maximal vasodilation of the coronary
microcirculation is generally assumed to occur during myocardial ischemia induced by rises …

Objectives. The aim of this study was to quantitatively measure regional and global myocardial
blood flow and coronary reserve in hypertensive patients without coronary artery disease …

Objectives We evaluated regional diastolic function by pulsed Doppler myocardial mapping
for the detection of left ventricular ischemia during pharmacologic stress testing. Background …

We investigated the use of visual and quantitative technetium 99m tetrofosmin ECG-gated
single-photon emission tomography (SPET) for the assessment of regional myocardial wall …

Methods: In 82 patients, 93 rest or stress SPECT studies were performed using 201T1and
99mTc-hexakis-2-methoxyisobutyl isonitrile to evaluate 99 vascular territories with implanted …

OBJECTIVES The aim of this study was to quantitatively evaluate myocardial flow reserve in
patients early after coronary stent implantation using positron emission tomography. …

Scintigraphy with bone-seeking tracers is used frequently for evaluation of focal abnormalities
of bone metabolism. Tracer uptake depends on multiple physiological and pathological …

In this study we examined the functional capacity of unseparated, IL-2R positive and IL-2R
negative leukocytes infiltrating BN rat hearts or kidneys grafted into allogeneic LEW rats. …

Numerous stress perfusion studies have demonstrated that coronary angioplasty despite
successful dilation of a flow-limiting stenosis fails to normalize coronary flow reserve within …

The lack of attenuation correction (AC) is one of the major limitations for quantitative analysis
of conventional SPECT images. Multihead SPECT allows for simultaneous transmission …
