Sensitivity and Specificity of Dual-Isotope 99mTc-Tetrofosmin and 123I Sodium Iodide Single Photon Emission Computed Tomography (SPECT) in Hyperparathyroidism

Sensitivity and Specificity of Dual-Isotope 99mTc-Tetrofosmin and 123I Sodium Iodide Single Photon Emission Computed Tomography (SPECT) in Hyperparathyroidism

PURPOSE Despite recommendations for 99mTc-tetrofosmin dual tracer imaging for hyperparathyroidism in current guidelines, no report was published on dual-isotope 99mTc-tetrofosmin and 123I sodium iodide single-photon-emission-computed-tomography (SPECT). We evaluated diagnostic accuracy and the impact of preoperative SPECT on the surgical procedures and disease outcomes. METHODS Analysis of 70...

[Diagnostic and prognostic evaluation of unstable angina pectoris using ECG-gated single photon emission computed tomography (SPECT) with 99mTc-tetrofosmin].

PURPOSE The purpose of this study is to the diagnostic accuracy and the value as prognostic predictors based on the perfusion and/or functional analysis using the QGS program on 99mTc-tetrofosmin gated SPECT (Tf-QGS-SPECT) in patients with unstable angina pectoris (UAP) who admitted to the CCU. METHODS Fifty seven consecutive patients (37 males and 20 females, mean age: 62 +/- 7 years) with s...

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...

Single-photon emission computed tomography (SPECT) and intractable epilepsy.

TAPANI TIKKAKOSKI Editor In patients with intractable epilepsy refractory to medication, surgical treatment may be needed. Magnetic resonance imaging (MRI) is an essential neuroimaging tool in assisting the identifi cation of epileptogenic lesions. MRI at 3T has been found to perform better than 1.5T in terms of image quality, detection of structural lesions, and characterization of lesions. Th...
