99mTc-3PRGD2 single-photon emission computed tomography/computed tomography for the diagnosis of choroidal melanoma

Monte Carlo Study of the Effect of Backscatter Materail Thickness on 99mTc Source Response in Single Photon Emission Computed Tomography

Introduction SPECT projections are contaminated by scatter radiation, resulting in reduced image contrast and quantitative errors. Backscatter constitutes a major part of the scatter contamination in lower energy windows. The current study is an evaluation of the effect of backscatter material on FWHM and image quality investigated by Monte Carlo simulation. Materials and Methods SIMIND program...

The value of 99mTc-methylene diphosphonate single photon emission computed tomography/computed tomography in diagnosis of fibrous dysplasia

BACKGROUND Fibrous dysplasia (FD) is a rare benign bone disorder in which the normal bone is replaced by immature fibro-osseous tissue. However, some case reports have reported that FD showed significantly increased 99mTc-methylene diphosphonate (99mTc-MDP) uptake on whole-body bone scintigraphy (WBS), which may mimic bone metastasis or skeletal involvement of the patients with known cancer. Th...

Positron emission tomography and single photon emission computed tomography.

Neuroimaging techniques have had a dramatic impact on the evaluation and treatment of patients with epilepsy. In order to take full advantage of their potential, it is important to place them in clinical and electrophysiological context and to understand their technical limitations. Positron emission tomography with 18F-2-deoxyglucose and single photon emission computed tomography can provide v...
