Scintigraphy Articles

Prostate-specific membrane antigen (PSMA) SPECT imaging in prostate cancer (PCa) could be a valuable alternative in regions where access to PSMA-PET imaging is restricted. [99mTc]Tc-PSMA-I&S is a new 99mTc-labeled PSMA-targeting SPECT agent, initially developed for radio-guided surgery.

Current investigations of stomach function are based on small test meals that do not reliably induce symptoms and analysis techniques that rarely detect clinically relevant dysfunction. This study introduces the large 'Nottingham Test Meal' (NTM) for assessment of gastric motor and sensory function by non-invasive imaging.

Diuresis renography (DR) is widely used in the evaluation of hydronephrosis and hydroureter in infants and children. The goal of this provocative nuclear imaging examination should be to detect the hydronephrotic kidneys at risk for loss of function and development of pain, hematuria, and urinary tract infection.

Aim: The objective of this study was to estimate the absorbed doses to the normal organs and tumor lesions in metastatic castration-resistant prostate cancer (mCRPC) patients treated with indigenously developed 177Lu-PSMA-617 that could establish optimal treatment protocol with minimum risk to the dose-limiting organs.

We investigated whether scintigraphy was superior to radiography for detecting migrated seeds after brachytherapy for prostate cancer.

We studied 57 patients with early prostate cancer who were treated with free (125)I transperineal brachytherapy.

A 45-year old patient presented with prostate-specific antigen relapse after radical prostatectomy. Diagnostic workup revealed a (68)Ga-labeled prostate-specific membrane antigen-targeted ligand tracer uptaking nodule that was initially interpreted as lymph node metastasis but eventually identified as a splenunculus by scintigraphy with (99m)Tc pertechnetate-labelled heat-altered erythrocytes.

Bone metastases develop in several malignancies (multiple myeloma, breast, prostate and lung carcinoma) and cause several complications. The aim of this study was to search for new biomarkers to use in monitoring of bone metastatic disease with the use of xMAP technology.
