The added value of SPECT-CT in the detection of heterotopic ossification on bone scintigraphy.

Purpose: Heterotopic ossification (HO) is the abnormal osteogenesis in non-skeletal tissue. It can be difficult to detect, as it can mimic other conditions clinically and on imaging studies. The purpose of this study was to find the added value of SPECT-CT in accurate detection of HO.

Comparison of pinhole and high-resolution parallel-hole imaging for nodular thyroid disease.

Introduction And Objective: Pinhole has been the main standard collimator to be used for thyroid imaging. There has been a gradually increasing trend to replace pinhole with the use of high-resolution low-energy parallel-hole collimator with zoom in thyroid imaging. The objective of this study is to compare parallel-hole collimator acquisition of thyroid gland with that obtained by pinhole collimator to find the effect on the diagnostic information in nodular thyroid disease.

Impact of obesity on nuclear medicine imaging.

Obesity, with its alarming increase among adults and children, represents a significant health problem with serious medical, social, psychologic, and economic reverberations. The burden of this problem significantly affects the medical care system, including medical imaging. The effect of obesity on nuclear medicine imaging spans many aspects, from preimaging patient preparation to radiotracer administration, image acquisition, and image interpretation.
