Evaluation of heterotopic ossification maturity using SPECT/CT and PET/CT in preclinical model.
Nucl Med Biol
December 2024
Departments of Nuclear Medicine, College of Medicine, Kuwait University, Kuwait.
Background: Heterotopic ossification (HO) is the formation of bone within soft tissue where bone normally does not exist. In general, it is characterized by highly active tissue with high bone turnover and rapid bone formation. It is of an utmost importance to precisely identify and accurately diagnose the maturity of HO as early surgical intervention may result in its recurrence.

Objective: The objective of this retrospective study was to identify the uptake patterns and suggest a quantitative method to detect hyperostosis frontalis interna (HFI) on fluorine-18 sodium fluoride ([ 18 F]NaF) PET/computed tomography (CT).
Methods: Between January 2019 and December 2021, patients who underwent [ 18 F]NaF PET/CT with a BMI of 30 and above, were included. Three nuclear medicine consultants reviewed the studies to determine the presence and identify the uptake patterns of HFI.
Potential Pitfalls of Steatopygia on Bone Scintigraphy and the Added Value of Single Photon Emission Computed Tomography and Single Photon Emission Computed Tomography/Computed Tomography.

Article Synopsis
- The study aimed to assess how common steatopygia (fat distribution on the lower back) is in obese patients through bone scans and its impact on viewing the lumbar spine.
- It included patients with a BMI of 30 or more, with findings showing that 50% of obese patients and 80% of morbidly obese patients had steatopygia, affecting their spine scans.
- SPECT and SPECT/CT imaging significantly improved diagnostic clarity by reducing artifacts caused by steatopygia, allowing for better identification of spine abnormalities.
Reducing Radiation Exposure from PET Patients.

Nuclear Medicine Department, Faculty of Medicine, Kuwait University, Jabryia, Kuwait.
This study measured the typical emitted radiation rate from the urinary bladder of PET patients after their scan and investigated simple methods for reducing the emitted radiation before discharge. The study included 83 patients (63 F-FDG and 20 F-NaF patients). Emitted radiation from the patients' urinary bladder was measured with an ionization survey meter at a 1-m distance, presuming the urinary bladder to be the primary source of radiation.

The aim of this study is to investigate the relationship between brown adipose tissue (BAT) activation and myocardial fluorine-18-fluorodeoxyglucose ([F] FDG) uptake in terms of intensity and patterns. The patients were divided into two groups as follows: BAT and control groups. The BAT group consists of 34 cases that showed BAT uptake.
