Initial clinical experience with dedicated multi-pinhole (MPH) collimator for Tc-HMPAO brain perfusion SPECT.

Objective: Dedicated multi-pinhole (MPH) collimators have been successfully tested in selected clinical investigations. The aim of our work was to report initial experiences with an MPH collimator set designed for brain perfusion single photon emission tomography (SPECT).

Subjects And Methods: Ten patients underwent sequential technetium-99m-hexamethylpropyleneamineoxime (Tc-HMPAO) SPECT with a dual-head SPECT camera equipped with conventional low-energy parallel hole collimators (LEHR), and with a triple-head system equipped with MPH collimators.

[11C-choline PET/CT in the diagnosis of prostate cancer -- Hungarian experience].

11C-choline has been used in the diagnosis and follow-up of patients with prostate cancer for years. Choline PET/CT has been available in human care since March, 2014 in our country. Unfortunately this examination has not been reimbursed by the National Health Insurance so far.
