The Role of Neck Ultrasonography and Nuclear Imaging in the Diagnosis of Congenital Hypothyroidism.

December 2024
Department of Endocrinology, Madurai Medical College and Govt. Rajaji Hospital, Madurai, Tamil Nadu, India.
Introduction: Congenital hypothyroidism (CH) is the most common preventable cause of mental retardation, and the two important causes of CH are thyroid dysgenesis and dyshormonogenesis. Thyroid imaging is an integral part of identifying the specific aetiology of CH. We aimed to study the aetiological profile of CH and compare the imaging findings of ultrasonography (USG) and nuclear scintigraphy.

Objective: The appropriate clinical management of indeterminate small renal masses can be improved based on accurate risk stratification. This study aimed to investigate the impact of renal function on the uptake of technetium-99m (99mTc)-sestamibi, a widely available imaging agent that can be utilized to identify oncocytomas and other benign/indolent renal masses.
Methods: A retrospective cohort study was conducted, involving 100 consecutive patients who underwent 99mTc-sestamibi single-photon emission computed tomography/computed tomography.
Utility of a C-Spirulina Stable Isotope Gastric Emptying Breath Test in Diabetes Mellitus.

Division of Gastroenterology and Hepatology, Mayo Clinic, Rochester, Minnesota, USA.
Background: The carbon-13 spirulina gastric emptying breath test (GEBT) is approved to identify delayed, but not accelerated, gastric emptying (GE). We compared the utility of the GEBT to scintigraphy for diagnosing abnormal GE in patients with diabetes mellitus.
Methods: Twenty-eight patients with diabetes ate a 230-kcal test meal labeled with technetium 99 m and C-spirulina, after which 10 scintigraphic images and breath samples (baseline, 15, 30, 45, 60, 90, 120, 150, 180, 210, and 240 min) were collected on 2 occasions 1 week apart.
Radiation dose assessment and establishment of diagnostic reference levels for MDP Tc-99m bone scans: A multi-hospital study in Saudi Arabia.

January 2025
Medical Diagnostic Imaging Department, College of Health Science, University of Sharjah, Sharjah, United Arab Emirates.
Background: Bone scans using technetium-99m methylene diphosphonate (99mTc-MDP) are widely used in nuclear medicine for diagnosing various bone disorders. However, the radiation exposure associated with these procedures necessitates careful consideration and optimization.
Aim: This study aimed to evaluate radiation doses in terms of Effective Dose (ED) and establish Diagnostic Reference Levels (DRLs) for 99mTc-MDP bone scans in Saudi Arabia.
Computational insights into the redox properties and electronic structures of [Tc=O] complexes: Implications for Tc-radiopharmaceuticals.

Technetium-99m plays a pivotal role in nuclear medicine, offering unique IMAGING capabilities due to its favorable physical and chemical properties. This study investigates the redox behavior and electronic structures of three representative Tc(V) oxo complexes, [TcO(HMPAO)], [TcO(Bicisate)], and [TcO(DMSA)], using computational techniques. Employing relativistic density functional theory with the Zero-Order Regular Approximation (ZORA), we analyze singlet-triplet energy gaps, Gibbs free energy changes, and redox potentials in neutral and acidic environments.
