Several small molecules of PSMA ligands of inhibitors binding to the active site of PSMA were developed. [99mTc]Tc-PSMA-T4 is a new radiopharmaceutical (Polatom) for imaging loco-regional metastases and/or local relapse in patients with prostate cancer. The purpose of this work was to evaluate the clinical application of SPECT-CT imaging with [99mTc]Tc-PSMA-T4 in patients with recurrent prostate cancer.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Material and methods: &lt;/strong&gt;Thirty-six patients with prostate cancer, aged 60-80 years with biochemical relapse of PSA (ranged from 0.1 to 73 ng/mL) were included. Three patients were studied after tru-cut biopsy, hormonal and cytoreductive radiotherapy and 33 patients out of 36 - after radical treatment (total prostatectomy or definitive radiotherapy of the tumour). All of them underwent whole-body imaging examinations with subsequent target SPECT-CT studies of the pelvis, abdomen and/or chest, 1-3 hrs post i.v. administration of [99mTc]Tc-PSMA-T4. The average activity dose was 6.3 MBq/kg in a man of 70 kg. A Dual-head SPECT-CT gamma camera with a low dose CT scan (Symbia T2, Siemens) was used. The images were interpreted based on all other clinical and radiological data. Follow-up could be conducted in 11/36 patients during that period.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;Normal biodistribution of the radiopharmaceutical with high activity background was observed in the liver, spleen, kidneys, lacrimal and salivary glands, bowels and urinary bladder. Positive imaging for local relapse in the prostate bad was imaged in 21 patients, lymph node metastases - in 16 cases, bone lesions - in 10 cases, pulmonary metastases - in 2 cases, hepatic lesions were visualised in one of them and in another - adrenal suprarenal metastasis with intensive tracer uptake significant for overexpression of PSMA. There was a suspicion for local recurrences in 4 patients with negative MRT studies who were followed up. In 3 cases, previously treated bone metastases were partially negative without tracer uptake, only some progressive bone lesions were positive. Five patients were with negative results. Sensitivity was 84.37% (27/32), specificity - 100% (4/4) and accuracy - 86.11% (31/36).&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Conclusions: &lt;/strong&gt;In conclusion SPECT-CT imaging with [99mTc]Tc-PSMA-T4 could be applied in patients with prostate cancer for the diagnosis of recurrent disease to determine personalized treatment for each patient. Specific uptake of this tracer, depicted by SPECT-CT images has clinical importance of identifying and assessing PSMA expression before consideration of Radio Ligand Therapy (RLT) with [¹⁷⁷Lu]Lu-PSMA.

This issue hinders the exchange of obtained results across centers and stunts the development of repeatable and reproducible measurements. The unification and standardization of calibration and quality control techniques for quantitative SPECT/CT systems is currently a pressing need for nuclear medicine departments. The present study presents three selected physical quantities characterizing the quality of quantitative SPECT/CT system and seven quantities, currently used in the literature, to assess the quality of quantitative SPECT/CT images. The measurement of these parameters requires the use of standard gamma camera software for QC, external programs for quantitative analysis of recorded data and clinical software.

There is an increasing number of case studies which report the significance of ventilation/perfusion scintigraphy in the diagnosis of pulmonary embolism in COVID-19 patients [1, 2]. Since most of the patients in Poland were managed in an outpatient setting, this population has been excluded from many studies and its characteristics are not well-documented. Dhawan et al. [3] emphasize the importance of the evaluation of the prevalence and extent of perfusion abnormalities in survivors of COVID-19 through the whole spectrum of illness, from non-hospitalised patients to those in the intensive care unit (ICU). We report a case series of three patients after recovery from COVID-19, who underwent lung perfusion SPECT/CT. Scintigraphic examinations were performed after administration of 99mTc-Makro-Albumon with an activity of about 2 MBq/kg of patient’s body weight. All patients were examined using Symbia Intevo Bold with a protocol including SPECT/CT acquisition with the following parameters: LEHR collimator, 360 degrees, 120 projections, time per projection 15 sec, matrix 128x128; low-dose CT protocol. The examinations were performed to assess lung lesions in these patients. All patients were diagnosed through RT-PCR for SARS-CoV2 and were presenting mild-to-moderate symptoms. Treatment was symptomatic, including paracetamol and ibuprofen in all patients and additional azithromycin in case of Patient 1. None of them required hospitalization.
