BMIPP SPECT in cardiac sarcoidosis: A marker of risk?

Dual radioisotopes simultaneous SPECT of 99mTc-tetrofosmin and 123I-BMIPP using a semiconductor detector.

Objective(s): The energy resolution of a cadmium-zinc-telluride (CZT) solid-state semiconductor detector is about 5%, and is superior to the resolution of the conventional Anger type detector which is 10%. Also, the window width of the high-energy part and of the low-energy part of a photo peak window can be changed separately. In this study, we used a semiconductor detector and examined the ef...

Review of transmission scanning configurations in cardiac SPECT

The diagnostic accuracy of single photon emission computed tomography (SPECT) is profoundly influenced by attenuation phenomenon. Soft tissue attenuation degrades cardiac SPECT image quality, thereby decreasing the possibility of the detection of the lesions. A variety of correction techniques based on different assumptions have been used to reduce the impact of attenuation. Several types of sy...

Evaluation of attenuation correction process in cardiac SPECT images

  Introduction: Attenuation correction is a useful process for improving myocardial perfusion SPECT and is dependent on activity and distribution of attenuation coefficients in the body (attenuation map). Attenuation artifacts are a common problem in myocardial perfusion SPECT. The aim of this study was to compare the effect of attenuation correction using different a...

Cardiac involvement in sarcoidosis

Sarcoidosis is a systemic disease of unknown aetiology characterised by the formation of noncaseating epitheloid cell granulomas, which can occur in virtually any organ. Cardiac involvement is of critical importance, due to the poor prognosis if this organ manifestation is left undiagnosed and untreated. Early initiation of therapy seems to be associated with a good prognosis; therefore, the di...
