Over the past four years, Ga-fibroblast activation protein inhibitor (FAPI) positron emission tomography/computed tomography (PET/CT) has been established at a tertiary cancer care facility in Jordan. This retrospective study aims to explore tracer uptake metrics across various epithelial neoplasms, identify diagnostic pitfalls associated with Ga-FAPI PET/CT, and evaluate the influence of Ga-FAPI PET/CT staging results on changes in therapeutic intent compared to gold standard molecular imaging modalities. A total of 48 patients with biopsy-confirmed solid tumors underwent 77 Ga-FAPI PET/CT examinations for molecular imaging assessment, encompassing neoplasms originating from the gastrointestinal tract, head and neck, hepatobiliary system, pancreas, breast, and lung.

Gallium-Fibroblast activation protein inhibitor (Ga-FAPI) positron emission tomography/computed tomography (PET/CT) is increasingly used for evaluating various epithelial neoplasms. Despite addressing some pitfalls, many remain unacknowledged. This report details a 77-year-old man with suspected pancreatic malignancy who underwent a Ga-FAPI PET/CT scan post-gastroduodenal coil embolization for upper gastrointestinal bleeding.

Article Synopsis
  • - Bronchial carcinoids are low-grade neuroendocrine tumors that grow slowly and can spread to lymph nodes; the case presented involves one alongside a benign bronchocele, making diagnosis challenging.
  • - Chest CT scan initially identified the endobronchial mass but lacked clear diagnostic insights, leading to an endobronchial biopsy that confirmed it was a lung carcinoid tumor.
  • - A Ga-DOTATOC PET/CT scan provided better evaluation, showing the carcinoid mass with high expression while revealing the benign bronchocele with low expression, emphasizing the role of somatostatin receptor imaging for accurate assessment.

Article Synopsis
  • * A 68-year-old man experienced left arm pain, leading to his diagnosis of RCC and the discovery of metastases in the right kidney and left humerus through imaging.
  • * The use of F-fluorodeoxyglucose PET/CT imaging revealed not only the expected metastases but also an unexpected thyroid cartilage lesion, emphasizing the need for advanced imaging in assessing RCC.

Background: Chimeric antigen receptor (CAR) T-cell therapy has attracted considerable attention since its recent endorsement by the Food and Drug Administration, as it has emerged as a promising immunotherapeutic modality within the landscape of oncology. This study explores the prognostic utility of [F]Fluorodeoxyglucose positron emission tomography ([F]FDG PET) in lymphoma patients undergoing CAR T-cell therapy. Through meta-analysis, pooled hazard ratio (HR) values were calculated for specific PET metrics in this context.

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.

Extramedullary myelomatous disease is an aggressive condition where clonal plasma cells proliferate outside the bone marrow, allowing independent survival. This state is generally associated with negative outcomes. A 65-year-old woman presented with progressive bilateral hypochondrial pain, was initially misattributed to an inflammatory etiology, and was consequently managed with corticosteroid therapy.

Background: The incidence of thyroid cancer is on the rise worldwide, with childhood exposure to radiation being the sole acknowledged catalyst for its emergence. Nonetheless, numerous other factors that may pose risks are awaiting thorough examination and validation. This retrospective study aims to explore the malignancies linked to thyroid cancer and contrast the survival rates of those afflicted with a solitary tumor versus those with multiple primary neoplasms (MPN).

The objective of this retrospective study is to assess the effectiveness and safety of two beta-emitting prostate-specific membrane antigen (PSMA) radioligands, [Lu]Lu and [161Tb]Tb, in heavily treated patients with metastatic castration-resistant prostate cancer (mCRPC). A total of 148 cycles of beta-emitting PSMA radioligand therapy were given to 53 patients at a specialized cancer care center in Amman, Jordan. This treatment was offered following the exhaustion of all prior treatment modalities.
