A New Era for PET/CT: Applications in Non-Tumorous Renal Pathologies.

Non-tumorous kidney diseases include a variety of conditions affecting both the structure and function of the kidneys, thereby causing a range of health-related problems. Positron emission tomography/computed tomography (PET/CT) has emerged as a potential diagnostic tool, offering a multifaceted approach to evaluating non-tumorous kidney diseases. Its clinical significance extends beyond its conventional role in cancer imaging, enabling a comprehensive assessment of renal structure and function.

From SPECT/CT towards absolute quantification? - the case of unilateral condylar hyperplasia of the mandible.

Background: Unilateral condylar hyperplasia (UCH) of the mandible is a rare condition characterized by asymmetric growth of the mandibular condyles. Bone scintigraphy with SPECT(/CT) is commonly used to diagnose UCH and guide treatment. Still, varying results have been reported using the traditional threshold of 55%:45% in relative tracer uptake.

Incidence of exclusive extrapelvic skeletal metastasis in prostate carcinoma on bone scintigraphy.

Background: Bone is one of the common sites of metastasis from prostate carcinoma. Bone scintigraphy (BS) is one of the most sensitive imaging modalities currently used for bone metastatic work-up. Skeletal metastasis in prostate carcinoma commonly involves pelvic bones but rarely involves extrapelvic-extraspinal sites.

Assessment of regional and total skeletal metabolism using F-NaF PET/CT in patients with chronic kidney disease.

Objective: The study aims to assess regional and total bone metabolic activity in patients with chronic kidney disease using Na[F]F PET and correlation between semi-quantitative indices and blood parameters.

Methods: Seventy-two subjects (mean age 61.8 ± 13.
