Diagnostic yield of a novel tracer 68Ga-citrate in sarcoidosis patients.

Background: Sarcoidosis is a granulomatous disease of unknown origin. Conventional laboratory and imaging modalities may lead to equivocal conclusions for sarcoidosis diagnosis. 68Ga-citrate PET/CT has been utilized in the diagnosis of inflammatory and infectious diseases due to its beter  performance.

99mTc-PYP and 68Ga-FAPI PET/CT Images of Hereditary Transthyretin Amyloidosis With Cardiac Involvement.

Amyloidosis is a protein misfolding disorder characterized by the extracellular deposition of insoluble amyloid fibrils, derived from abnormally folded proteins. These fibrils disrupt tissue structure and function, leading to organ dysfunction. The condition encompasses various subtypes, each associated with distinct precursor proteins and clinical manifestations.

US-guided percutaneous ablation of thyroid nodules with LU-MAA (LUTMA) - Feasibility study.

Purpose: The main purpose is to evaluate the safety, and efficacy of Lutetium labeled macroaggregated albumin (LUTMA) ablation of thyroid nodules.

Materials And Methods: Patients with confirmed benign nodules who were not candidate or did not accept surgery were enrolled. Under ultrasonography (USG) guidance, LUTMA which was produced in our department, was administered into the nodules.

Zr-leukocyte labelling for cell trafficking: in vitro and preclinical investigations.

Background: The non-invasive imaging of leukocyte trafficking to assess inflammatory areas and monitor immunotherapy is currently generating great interest. There is a need to develop more robust cell labelling and imaging approaches to track living cells. Positron emission tomography (PET), a highly sensitive molecular imaging technique, allows precise signals to be produced from radiolabelled moieties.

Hybrid Ga-68 prostate-specific membrane antigen PET/MRI in the detection of skeletal metastasis in patients with newly diagnosed prostate cancer: Contribution of each part to the diagnostic performance.

Purpose: Bone metastasis is essential in patients with prostate cancer (PCa) as it determines prognosis and survival. Hybrid PET/MRI allows simultaneous acquisition of PET and MRI data, thus combining the strength of both technologies allows the detection of bone marrow metastases that are missed by PET/CT. In this retrospective study, we aimed to evaluate the diagnostic efficiency of hybrid PET/MRI with Ga-68 prostate-specific membrane antigen (PSMA) in detecting skeletal metastases in newly diagnosed PCa patients and compared the effectiveness of stand-alone PSMA PET reviewing versus stand-alone whole-body (WB) MRI evaluation.
