Article Synopsis
- Ra imaging is essential for assessing the effectiveness of treatments for bone metastasis in castration-resistant prostate cancer (CRPC), and a study was conducted to develop a quantitative imaging protocol with effective settings for the gamma camera.
- The optimal energy windows for Ra imaging were determined to be 85 keV ± 20%, 154 keV ± 10%, and 270 keV ± 10%, using a specific algorithm which balances contrast and noise for image reconstruction.
- The calibration of gamma camera showed reliable quantification for Ra concentrations above 8 kBq/ml, with a maximum error of 18.8% in small lesions, highlighting some limitations at lower concentrations.
Objective: Dynamic renal scintigraphy remains the gold standard for assessing differential renal function (DRF). Recently, technetium-99m-ethylenedicysteine (Tc-EC) was shown to be valuable and had similar quality images as technetium-99m-mercaptoacetyltriglycine (Tc-MAG3). However, its reproducibility has never been confirmed.

Routine screening for this disorder in maternity hospitals in industrialized countries, for nearly 40 years, has permitted early treatment and thereby helped to prevent its physical and mental complications. Neonatal hypothyroidism affects approximately 1 in 3000 births.

Hypertension resolved immediately after complete surgical resection of the tumor with an uneventful follow-up (24 months at the present time).

The present study aimed at evaluation of the diagnostic value of WBCs scintigraphy in suspicion of mediastinitis relapse after prior surgical revision.
Methods And Results: Multiple planar incidences of the chest were acquired 4 and 20 hours after injection of labeled WBC in 43 patients.
