thallium media in cardiac catheterization

UNLABELLED: Iodine-123-metaiodobenzylguanidine ([123I]MIBG) has been used to evaluate the cardiac sympathetic nervous system, particularly that of the left heart. To clarify whether the right ventricular (RV) sympathetic neuronal function could be evaluated by [123I]MIBG myocardial imaging, we applied the technique in patients with pulmonary hypertension that was associated with either chronic pulmonary diseases or pulmonary vascular diseases. METHODS: All patients underwent right heart catheterization, and right heart hemodynamics were determined during a clinically stable state...

Thallium-201 (201Tl) stress-redistribution/reinjection imaging provides a reliable diagnostic approach in patients evaluated for myocardial ischaemia. Immediate reinjection of 201Tl after completing the stress images followed by imaging 1 h later shortens the investigation time to 2.5 h and may provide a novel approach. In this study, we validated the immediate reinjection approach in the assessment of myocardial perfusion and viability using contrast angiographic findings as the reference standard. We studied 114 patients with documented cardiac catheterization data using quantitative planar 201Tl stress/immediate reinjection imaging...

To study the potential usefulness of 99mTc-methoxy isobutyl isonitrile (99mTc-MIBI) as a substitute for 201Tl in assessing patients with ischaemic heart disease, 24 patients underwent 1 day rest and exercise 99mTc-MIBI single photon emission computerised tomography (SPECT) 1 week after SPECT exercise 201Tl. All patients were catheterized within 1 month after myocardial imaging. In 17 patients, resting first pass radionuclide angiography (FPRNA) was performed with 99mTc-MIBI. The heart to lung ratio for 99mTc-MIBI and 201Tl was calculated both at rest and exercise...

Myocardial contrast echocardiography was performed, before and after successful elective percutaneous transluminal angioplasty (PTCA) of a main coronary artery, in 35 patients (31 men, 4 women; mean age 56 +/- 6 years). After intracoronary injection of microbubbles-containing 2 ml iopromide, contrast half-life (t/2) and maximal echo-intensity (Imax) in the myocardial region supplied by the target vessel were measured. While t/2 decreased from 8.3 +/- 5.4 s to 5.7 +/- 3.3 s (P less than 0.0002), mean Imax remained unchanged (27...

A microtiter technique was used for determination of the sensitivity of Mycoplasma hyosynoviae to antibiotics and other drugs. Use of a biphasic agar-broth medium in microtiter plates allowed direct visualization of growth. Results were more reproducible with this system than when broth alone was used and evaluation based on color change was required. Attempts to adapt the test for use with Mycoplasma hyorhinis were not successful. Minimal inhibitory concentrations of 12 drugs and drug combinations for 12 strains of M...
