    Thallium 201 stress testing using a supine bicycle (Tl-SB) is less accurate for diagnosing coronary artery disease than traditional treadmill testing (Tl-TM). Tl-TM demonstrated superior sensitivity and specificity in patient evaluations.

    Area of Science:

    • Cardiology
    • Nuclear Medicine
    • Diagnostic Imaging

    Background:

    • Thallium 201 stress testing is a common method for diagnosing coronary artery disease.
    • While treadmill testing (Tl-TM) is standard, supine bicycle-ergometer-exercise thallium 201 testing (Tl-SB) has been explored as an alternative.
    • The comparative accuracy of Tl-SB versus Tl-TM requires further investigation.

    Purpose of the Study:

    • To evaluate the diagnostic accuracy of supine bicycle-ergometer-exercise thallium 201 testing (Tl-SB) for coronary artery disease.
    • To compare the accuracy of Tl-SB with traditional treadmill thallium 201 testing (Tl-TM).
    • To correlate the results of both testing methods with cardiac catheterization findings.

    Main Methods:

    • Fifty patients with suspected coronary artery disease underwent both Tl-SB and Tl-TM in a randomized sequence.

  • Cardiac thallium kinetics, including myocardial uptake and washout, were analyzed from immediate and delayed imaging.
  • Results were compared against gold-standard cardiac catheterization data.

    • Main Results:

    • Thallium 201 treadmill testing (Tl-TM) yielded significantly higher maximal pulse rates and pulse-pressure products compared to Tl-SB.
    • Significant differences in cardiac thallium kinetics were observed, with Tl-TM showing greater initial myocardial uptake and thallium 201 washout.
    • Thallium 201 treadmill testing (Tl-TM) demonstrated significantly higher sensitivity and specificity than Tl-SB in diagnosing coronary artery disease when compared to catheterization.

    Conclusions:

    • Thallium 201 treadmill testing (Tl-TM) is more accurate than supine bicycle-ergometer-exercise thallium 201 testing (Tl-SB) for the evaluation of coronary artery disease.
    • Supine bicycle testing results in different thallium kinetics and is less effective in detecting coronary artery disease compared to treadmill testing.
    • Treadmill-based thallium 201 stress testing remains the preferred method for accurate diagnosis of coronary artery disease.
