Joel:
You are correct. All three companies sell
Tl-201.

Stress Test
Tom,
The test you are referring to is a myocardial perfusion study. The two
compounds are Cardiolite(r) a Tc-99m-labeled compound (or its competitor,
Tc-99m tetrafosmin or Myoview), and Tl-201 (as thallous chloride). The
two compounds are commonly used in sequence to measure the blood flow to the
heart wall under resting and stressed conditions respectively. The
mismatch between the two indicates the presence of flow limitations to specific
portions of the heart muscle. For more information, look at
www.cardiolite.com. Cardiolite is a product of Bristol-Myers Squibb
Medical Imaging. Myoview is a product of Amersham Health and distributed
in the US by the Malinckrodt Imaging unit of Tyco
Healthcare. Tl-201 is available from all three companies, I believe.

Subject: Dual Radionuclide Stress Test
A friend asked me about a dual radionuclide stress test. He said some
previous tests had identified an enlarged heart muscle. Does anyone have
any information on this test like - what it is - what radionuclides are
used - how the test is done - and what data is provided to determine what?
