Myocardial positron emission tomography (PET) using N-13-ammonia (NH3) and F-18-fluorodeoxyglucose (FDG) was performed in 16 patients with myocardial infarction to assess myocardial blood flow and glucose utilization. These PET data were also compared by left ventriculography. N-13-ammonia PET study

To evaluate myocardial blood flow and glucose utilization, N-13 ammonia (NH3) and F-18 deoxyglucose positron emission tomography scanning was performed in 22 patients with previous anterior wall myocardial infarction, using a high-resolution, multi-slice, whole-body scanner. The N-13 ammonia study

Reversible defect of 123I-15-(p-iodophenyl)-9-(R,S)-methylpentadecanoic acid indicates residual viability within infarct-related area.

To evaluate the relationship between the reversible defect of 123I-15-(p-iodophenyl)-9-(R,S)-methylpentadecanoic acid (9MPA) and residual viability within an infarct-related area, we performed resting single photon emission computed tomography (SPECT) with 9MPA and positron emission tomography (PET)

OBJECTIVE To investigate the relations between myocardial metabolism and the kinetics of thallium-201 in myocardial scintigraphy. METHODS 46 patients within six weeks after the onset of acute myocardial infarction underwent resting myocardial dual isotope, single acquisition, single photon emission

Hypoperfused myocardium with increased uptake of 18F-fluorodeoxyglucose (FDG) is considered to be ischemic but viable myocardium. However, the significance of a more severe defect of FDG than of 13N ammonia (NH3) (i.e., reverse flow-metabolism mismatch) is not well understood. METHODS To study a

Reciprocal ST-segment depression associated with exercise-induced ST-segment elevation indicates residual viability after myocardial infarction.

OBJECTIVE We evaluated the clinical significance of reciprocal ST-segment depression associated with exercise-induced ST-segment elevation for detecting residual viability within the infarcted area. BACKGROUND Although the relation between residual viability and exercise-induced ST-segment elevation

OBJECTIVE We evaluated the relation between increased fluorine-18 deoxyglucose (FDG) uptake in remote normoperfused areas and acute ischemic events in patients with ischemic heart disease. METHODS We performed nitrogen 13 ammonia (NH3) and FDG positron emission tomography (PET) on 67 patients (46

A reverse flow-metabolism mismatch pattern: a new marker of viable myocardium with greater contractility during dobutamine stress than myocardium with a flow-metabolism mismatch pattern.

Few studies have investigated the contractility of myocardium with a reverse flow-metabolism pattern; that is, greater uptake of nitrogen- 13-ammonia (NH3) than fluorine- 18-fluorodeoxyglucose (FDG) on positron emission tomography (PET). This study examined the contraction thickening represented by
