Notes

Molecular genotyping associated with 20 N. anthracis stresses separated within Far eastern Siberia and Far east.
Increased activity of the initial
I regimen reduced total medical expenditure significantly for unilateral, and mildly for bilateral total thyroidectomy both with initial 30-99mCi
I.

For patients with specific thyroidectomy for differentiated thyroid cancer, a high initial regimen of
I treatment is more effective than the low activity regimen. An increased activity of the initial
I regimen significantly reduced the total treatment number and medical expenditure.

Gallium-68-prostate-specific membrane antigen positron emission tomography/computed tomography (
Ga-PSMA PET/CT) has become a well-established imaging method for the evaluation of patients with prostate cancer. However, several cases have revealed PSMA uptake in a large variety of conditions other than prostate cancer. Prostate-specific membrane antigen uptake in thyroid cancer has also been reported. The aim of the present study was to systematically investigate the prevalence and clinical significance of thyroid incidental findings in patients undergoing
Ga-PSMA PET/CT.

We retrospectively identified all patients referred for
Ga-PSMA PET/CT at the Department of Nuclear Medicine, Aalborg University Hospital, Denmark between May 2015 and May 2019. Patients with increased PSMA uptake in the thyroid gland were included in the analysis. Follow-up included imaging, biochemical, and/or histopathological collected over six months.

A total of 341 patients were included. Increased
Ga-PSMA uptake in the thyroid gland was observed in 13 patients (4%). Focal uptake was observed in seven patients, diffuse uptake in five patients and mixed focal and diffuse uptake in one patient. Malignancy was verified in two patients (2/13 patients, 15%), both patients with focal PSMA uptake.

Gallium-68-PSMA thyroid incidental findings are rare in prostate cancer patients. However, cases of focal PSMA uptake in the thyroid gland should be further investigated, as these findings may represent metastatic or primary malignancy of the thyroid gland.

Lutetium-177 (
Lu) prostate specific membrane antigen (PSMA) radionuclide therapy (RNT) is an effective and safe treatment option in patients with metastatic castration resistant prostate cancer (mCRPC). The first aim of this study was to determine RNT response rate. IMT1B RNA Synthesis inhibitor The second and main aim of this study is measure overall and progression-free survival (OS and PFS) and to determine the factors have effect on OS and PFS.

Patients with mCRPC had
Lu PSMA RNT every 6-8 weeks. Therapy response of each cycle determined wit PSA after 6-8 weeks. Overall survival and PFS were measured, then effects of age, Gleason grade, local recurrence, extraabdominopelvic located lymph node metastasis, visceral metastasis, prostate specific antigen (PSA) changing after the first RNT, pretreatment PSA, hemoglobin (Hb), alkaline phosphatase (ALP) and lactate dehydrogenase (LDH) values on survivals were determined.

Forty-five patients were treated with total of 164 cycles of RNT. Fifteen patients (33%) had PSA decline of ≥50%, 23 patients (51%) showed any PSA decline and 20 patients (44%) showed PSA increase of ≥25%. Median OS and PFS were 17,1 months and 7,4 months. Patients had any or ≥50% PSA response after the first cycle, lower initial ALP (<120U/L) had longer OS and PFS. Patients had normal Hb showed longer OS and patients had lower initial PSA (<51ng/mL) had longer PFS. Patients had PSA progression of ≥25% had shorter OS and PFS.

Prostate specific antigen response after the first cycle, lower initial ALP is related to longer OS and PFS. Normal pretreatment Hb is a predictor of longer OS and lower initial PSA is related to longer PFS. Prostate specific antigen progression after the first cycle causes shorter OS and PFS.

The aim of this study was to validate the optimal scatter correction method and scatter estimation window setting in terms of image quality and quantitative accuracy for quantitative indium-111 (
In)-pentetreotide SPECT imaging.

We used a positron emission tomography/computed tomography (PET/CT) phantom to validate image quality and quantitative accuracy, and the SPECT images were acquired by the multi-energy window (MEW) method. The scatter estimation was performed using four kinds of energy windows (MEW1, MEW2, MEW3, and MEW4). Scatter correction was also performed using a dual-energy window (DEW) for comparison with MEWs. Image quality was assessed using percent contrast (% contrast) and background variability, and quantitative accuracy was assessed using the mean standardized uptake value (SUVmean) with hot spheres.

In the quantification, all MEW settings approached the theoretical SUVmean (MEW1, 0.99±0.06; MEW2, 0.99±0.05; MEW3, 1.00±0.08; MEW4, 0.97±0.12) in contrast to DEW (0.88±0.05). The SUVmean value for scatter correction of both photopeaks for a 28 mm sphere showed the smallest difference from the theoretical value.

The scatter correction method that gave optimal image quality and quantitative accuracy was MEW3 with two 20% energy windows (one over each photopeak) and four adjacent 3% scatter estimation windows (one on each side of the two photopeaks).
