The detection rate of NEN lesions was determined according to histopathological classification by primary site and by organ. Results: At least one NEN lesion was detected in 73% (91/125) with a positive Krenning score of ≥2 in SRS. The detection of abdominal NENs (gastrointestinal tract, 38; pancreas, 62; and others, 14) was 89% (49/55) for neuroendocrine tumor (NET)-grade (G) 1, 78% (32/41) for NET-G2, 66% (2/3) for NET-G3, 31% (4/13) for neuroendocrine carcinoma (NEC), 100% (1/1) for mixed neuroendocrine–non-neuroendocrine neoplasm, and 0% (0/1) for non-classified NEN. That of thoracic NENs was 33% (2/6) for typical carcinoid tumor and 40% (2/5) for atypical carcinoid tumor. For a total of 226 organ lesions, hepatic lesions were 76% (58/76); pancreatic lesions, 61% (31/51); lymph node lesions, 77% (27/35); bone lesions, 83% (20/24); duodenal lesions, 82% (9/11); and other lesions, 41% (11/27).

Therefore, the aim of this study was to assess the value of 68Ga-DOTATATE scan in detecting NETs.Methods: This was a cross-sectional study. All patients with a pathologically confirmed NET tumor referred to Masih Daneshvari Hospital affiliated to Shahid Beheshti University of Medical Sciences entered the study. Patients underwent a 68Ga-DOTATATE PET/CT. All statistical analysis were performed by SPSS software version 18.Results: Forty patients with a mean age of 48.1±15.80 years entered the study. Twenty-one (52.5%) were male and 19 (47.5%) female. In the studied patients, neuroendocrine tumor was present in 19 cases (47.5%) in pancreas and gastrointestinal tract, 9 (22.5%) in lung, 3 (7.5%) in mediastinum and adrenal gland, 6 cases (5%) in liver and 3 other sites. There was no significant association between mean age and gender with primary location of the tumor. The meanSUVmax was 11.62±20.02 and the the mean tumor size was 38.25±31.35 mm. The mean size of the metastasis was 40.55±24.53 mm. The mean percentage of ki-67 was 12.54±18.40. There was no significant correlation between SUVmax of the lesion and age (r=0.063, P=0.701), tumor size (r=-0.63, P=0.067) or Ki-67 (r=0.011, P=0.960).

Methods: 67 patients with differentiated thyroid carcinoma were included in this study. The findings of 18F-FDG PET/CT imaging were compared with histo-pathology, follow up imaging, or clinical follow-up results.

Results: 30/67 patients had positive findings on 18F-FDG PET/CT; 28 were true-positive and 2 were false-positive. 18F-FDG PET/CT results were true-negative in 36 patients and false-negative in 1 patient.

In this research, we evaluated inter and intra-observer variation among ultrasonography reporters, based on ACR-TIRADS.Methods: In this retrospective study, 345 thyroid US images of 150 patients were reviewed. Three clinicians with at least 6-year experience in thyroid US reviewed the images twice at 6-8 weeks’ intervals. Composition, echogenicity, shape, margin, and echogenic foci based on ACR-TIRADS were reported, independently. Inter and intra-observer variations were calculated based on Cohen’s Kappa statistics.Results: 345 ultrasonography images of 150 patients with thyroid nodules (83 women and 67 men) with a mean age of 65 years were reviewed. Moderate to the substantial intra-observer agreement was achieved with the highest Kapa value in the category of shape (k=0.61-0.77). For TIRADS level, the moderate intra-observer agreement was observed (k=0.42-0.46). Inter-observer agreement for the US category of thyroid nodules was obtained slightly to moderate. Composition (k=0.42 and 0.51) and echogenicity (k=0.45 and 0.46) showed the highest overall agreement and margin showed the lowest overall agreement (k=0.18 and 0.19). In assessing TIRADS level of nodules, a fair agreement was obtained (k=0.23 and 0.29) .Conclusion: Moderate to substantial intra-observer agreement and slight to moderate inter-observer variation for evaluation of thyroid nodules; shows the need for a computer-aided diagnosis system based on artificial intelligence to assist our physicians in differentiating thyroid nodule characteristics based on explicit image features.

In this study, we evaluated the feasibility of sentinel lymph node mapping using intraoperative injection of radiotracer in nonseminomatous testicular cancer patients with history of orchiectomy who were candidate for retroperitoneal lymph node dissection (RPLND) in post-chemotherapy setting. Methods: Nine consecutive cases were included in the study. Technetium-99m-labelled phytate was injected in two divided doses in the stump of the spermatic cord, through transabdominal approach. A hand-held gamma probe was used for radio-guided retroperitoneal sentinel lymph node detection intraoperatively and confirming the location of the sentinel lymph nodes. Results: Detection rate and the false negative rate were estimated as the main indices. The detection rate was 6/9 (66%) and the false negative rate was 0/2 (0%). Location of the dissected sentinel lymph nodes were interaortocaval (2 patients), internal iliac (1 patient), external iliac (1 patient), common iliac (2 patients), and paraaortic (1 patient).

Six cases were confirmed SARS-CoV-2 by molecular tests. The following parameters were assessed: 1) lung involvement on co-registration CT as extension (laterality, number of lobes), pattern (ground-glass opacities/GGO, consolidations, mixed) and stage (early, progressive, peak, and absorption); 2) the maximum standardized uptake value (SUVmax) of lung lesions on 18F-FDG PET. Results: The involved lobes were 5 in 5 cases (3 confirmed SARS-CoV-2), 2-4 in 4 cases and 1 in 1 case. GGO were found in all patients; 3 cases also showed a combination of GGO and peripheral consolidations (mixed). Five cases were suggestive for an early stage of interstitial pneumonia, 4 for progressive and 1 for peak. All the lung lesions showed increased FDG uptake.
