Myocardial Perfusion scan(Stress Thallium)
EASY & SAFE: NON-INVASIVE, OUT PATIENT PROCEDURE, NO DYE NO ALLERGY
FUNCTIONAL IMAGING: SHOWS BLOOD FLOW & VIABILITY; NOT JUST THE MECHANICAL BLOCK
TRUE FLOW PATTERN: REVEALS COLLATERALS & MICROVASCULAR CIRCULATION & CORONARY STEAL PHENOMENON
VIABILITY: STUNNED MYOCARDIUM, HIBERNATING MYOCARDIUM
MOST COMPREHENSIVE INVESTIGATION OFFERING MAXIMUM INFORMATION FROM SINGLE STUDY
PATIENT PREPARATION
6 Hrs. FASTING FOR THALLIUM IS ESSENTIAL. DISCONTINUATION OF BETA-BLOCKERS &
FRUSEMIDE FOR 72-48 HRS BEFORE EXERCISE STRESS
NO THEOPHYLLINE AND CAFFEINE BEFORE ADENOSINE STRESS
NO NITRATES PREFERABLY ON THE DAY OF EXERCISE STRESS
