Does radionuclide imaging improve diagnostic accuracy and surgical planning compared to conventional angiography in a patient with Bland-White-Garland syndrome?
Radionuclide imaging can provide superior anatomical and functional information compared to conventional angiography for surgical planning in adult Bland-White-Garland syndrome.

May assist orifice localization and functional assessment in Bland-White-Garland syndrome when angiography fails; leaves open whether it improves surgical planning.
In a 27-year-old man with Bland-White-Garland syndrome (anomalous origin of the left coronary artery from the pulmonary artery), comparison was made between conventional diagnostic techniques and radionuclide imaging for selection of surgical procedure and evaluating the outcome. Dynamic 99mTc imaging exactly located the left coronary artery orifice, which was not seen on angiography, thereby determining the surgical approach, and 123I study revealed that, despite absence of symptoms, the adrenergic activity of the heart was globally diminished, with limited response to revascularization.

Günaydın et al. (1997) conducted a case report in Bland-White-Garland syndrome (n=1). Radionuclide imaging (Dynamic 99mTc and 123I) vs. Conventional diagnostic techniques (angiography) was evaluated on Location of the left coronary artery orifice and evaluation of adrenergic activity.
