Brain imaging is performed using radiopharmaceuticals by single photon emission
computed tomography (SPECT) and positron emission tomography (PET). SPECT and PET …

BACKGROUND The present investigation was designed to obtain an absolute
measurement of myocardial blood flow and of its transmural distribution in ischemic heart …

METHODS: Using a previously described technique of selective intra-arterial intratumoral
injection of 99m Tc-labeled microparticles (macroaggregated albumin), we measured the …

Transmission computed tomography (CT) brain scans were compared with N-isopropyl (I-
123)-p-iodoamphetamine (IMP) single-photon emission computed tomography (SPECT) …

In order to obtain functional images of brain perfusion, we exploited a new concept, which is
to take advantage of the short half-life of a radioactive tracer. Under continuous intracarotid …

The application of radionuclides to the study of the cardiovascular system was first
investigated by Blumgart and Yens' and Blumgart and Weiss” nearly one-half century ago …

BACKGROUND Experimental data demonstrate the persistence of a transmural vasodilator
reserve in the face of depressed resting myocardial perfusion. The present study was …

[en] Nuclear cardiology methods have had less impact upon pediatric cardiology than upon
adult cardiology. Most pediatric heart disease results from congenital malformations of the …

In a previous issue of Heart, Verttukattil and colleagues presented a study of intrapulmonary
arteriovenous shunting after a superior cavopulmonary anastomosis using radionuclide …

✓ Abnormal distribution of cerebral vascular flow was studied in a patient who had a
traumatic carotid-cavernous sinus fistula. Serial studies were performed using a method for …
