Background: Menopause is a natural and unavoidable circumstance in all women.s lives. Radioiodine therapy is the most popular method of treatment for differentiated thyroid carcinoma (DTC) worldwide. Considering these two, this study was designed to evaluate the menopausal age of DTC patients after a single dose of radioiodine therapy. Patients and Methods: This is a retrospective study analyzed in INMAS, Mitford, Dhaka, from January 2018 to December 2019 among 225 female patients with DTC who were referred for radioiodine therapy of different doses according to their clinical state (75 mci (2.7 GBq), 100 mci (3.7 GBq), and 150 mci (5.5 GBq). Results: Among 225 patients, about 47 women (20.9%) experienced menopause after radioiodine therapy during this study period. The average age of menopause in Bangladeshi women is 46.7 years (95% CI). In this study, the mean menopausal age of the study subjects was 44.1±2.6 years. About 13 patients experienced menopause after 75 mci (2.7 GBq) radioiodine therapy with a mean age of 45.6±2.2; 28 patients had menopause after receiving 100 mci (3.7 GBq) with a mean age of 44.4±2.7; and 6 patients had menopause after receiving 150 mci (5.5 GBq) of I-131 with a mean age of 44.1±2.0. The result was significant (P<0.05). Conclusion: This study reveals that the mean menopausal age of the patients after radioiodine therapy is lower than the mean menopausal age of normal Bangladeshi women.

Background: Differentiated thyroid cancers (DTC) are among the most curable cancers, with a 10-year survival rate of 80.95%. These patients are treated by radio-iodine ablation (RAIA). Post-therapy whole body scan (Rx WBS) is done 5-7 days after RAIA. Diffuse hepatic uptake (DHU) in RxWBS after radioiodine remnant ablation might indicate metabolization of radioiodine-marked thyroglobulin fragments. Objective: To analyze the diffuse hepatic uptake of 131I on a post-ablative 131I whole body scan by grading diffuse hepatic uptake and evaluating its clinical significance in the outcome of differentiated thyroid cancer (DTC). Patients and Methods: This is a prospective cohort study conducted in the thyroid division of the National Institute of Nuclear Medicine and Allied Sciences (NINMAS). A total of 67 low- and intermediate-risk groups of differentiated thyroid carcinoma (DTC) patients who were referred to the thyroid division for radio-iodine ablation after thyroidectomy were chosen for the study. Analysis of Rx WBS images was done. DTC patients were divided according to visually graded diffuse hepatic uptake or no hepatic uptake and followed up for one year. Follow-ups were done by measuring Tg and TgAb and doing high-resolution ultrasound (HRUS) of the neck. One year later, a diagnostic whole-body scan was done. Outcomes were disease-free (DF) conditions, persistent disease (PD), or recurrence. Results: Out of 67 patients, low-risk DTC was diagnosed in 32 and intermediate-risk in 35 patients. No high-risk group was included in this study. Two groups of patients were created: DHU and those with no hepatic uptake. Out of them, 48 patients had DHU. These findings and clinical data were compared and analyzed using SPSS, and a significant association (P = 0.40) was found between different doses of 131I administered for ablation and DHU. Age, histopathological type, lymph node involvement, ALT level, thyroid bed uptake, and fatty liver were found to be insignificant when compared with DHU. After 1 year of follow-up, 52 (76.6%) patients were disease-free (DF), and persistence disease (PD) and recurrence were present in 10 (14.9%) and 5 (7.5%) patients, respectively. Among DF patients, DHU was present in 79.2% of patients. The comparison of DHU and the outcome of the DTC showed an insignificant p value of 0.640. Conclusion: The ablative dose of 131I greater than 100 mCi had a positive relationship with DHU, which might be due to radiolabeled hormones. There was no significant association between DHU and the uptake in the thyroid bed, Tg values, age, stage of the disease, presence of local or distant metastases, recurrence, or survival.

Introduction: Hemangiomas are the most common benign tumors of the liver. Accurate diagnosis is crucial for differentiating hemangioma from other space-occupying lesions (SOLs) as management strategies differ significantly. Though FNAC is the gold standard investigative tool for the diagnosis of hepatic hemangioma, newer modalities like 99mTc labeled RBC liver SPECT now is being emerging diagnostic tool for tailoring the treatment of the patient with hepatic hemangioma. Objective: This study aims to evaluate the diagnostic performance of 99mTc labeled RBC liver SPECT over ultrasound in the definitive diagnosis of hepatic hemangiomas. Patients and Methods: A retrospective observational study of 52 patients was conducted who underwent both 99mTc labeled RBC liver SPECT scan and USG for hepatic lesion evaluation at NINMAS Dhaka from the period of 2022 to 2023. High-resolution ultrasonography was performed. Diagnostic measures, including sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and overall accuracy, were calculated for 99mTc labeled RBC SPECT and compared with USG. Imaging protocols, demographic data, and clinical characteristics were systematically analyzed. Results: Among 52 patients females were predominant. Representative images highlighted the enhanced blood pool activity in hepatic hemangiomas detected by RBC liver SPECT, which demonstrated superior sensitivity (92.3%) compared to ultrasound (76.9%). The specificity, positive predictive value (PPV), and overall accuracy were also higher for 99mTc labeled RBC SPECT and demonstrated significantly higher sensitivity (92.3%) compared to ultrasound (76.9%), with superior specificity, PPV, and overall accuracy. Conclusion: 99mTc labeled red blood cell liver SPECT holds a superior sensitivity and overall accuracy compared to ultrasound. It contributes to the evolving landscape of hepatic imaging and emphasizes the potential clinical utility of nuclear medicine techniques in the definitive diagnosis of hepatic lesions and also affects the clinical outcomes.

Background: In an effort to improve Bangladesh’s molecular imaging capabilities, the Institute of Nuclear Medical Physics (INMP), Savar, which is governed by the Bangladesh Atomic Energy Commission (BAEC), inaugurated its first FDG PET CT scan in September 2018. We will take a look at the first five years of FDG PET CT services provided to cancer patients at INMP in this article. Patients and Methods: The patients were advised to fast overnight before the day of the scan. A whole-body PET-CT scan was acquired with Philips 128-slice Ingenuity TF, one hour after intravenous injection of 18F FDG. Patients who had undergone FDG PET CT scans at INMP, Savar, from September 2018 to December 2023 were retrospectively included, and INMP report databases were reviewed for demographic analyses. Results: A total of 2879 patients underwent FDG PET CT scans for various clinical oncological and non-oncological indications from September 2018 to December 2023. In 2018, a total of 27 patients were scanned in the first year of the inauguration of FDG PET CT at INMP, Savar. Thereafter, 332 in 2019, 469 in 2020, 399 in 2021, 716 in 2022, and 936 in 2023 were scanned subsequently. A total of 12 patients underwent PET-CT scans for non-oncological indications; among them, tuberculosis was 75%. The top five most common primary malignancies were lymphoma (26.4%), carcinoma breast (21%), gastrointestinal carcinoma (9.6%), carcinoma lung (8.8%), and carcinoma ovary (4.6%). Among 762 lymphoma patients, non-Hodgkin’s lymphoma was 58.5%. The majority of patients were more than 61 years of age, with male predominance (52%). The percentage of DM was 34.0%, and dyslipidemia was 27%. Among 980 diabetic cancer patients, 78 had fasting hyperglycemia and required insulin injections before a PET-CT scan. Conclusions: Despite the COVID-19 pandemic and initial uncertainty about FDG availability, there has been a notable increase in FDG PET-CT scanning in INMP from 2018 to 2023. This considerable upsurge is extremely rewarding and plays a critical role in cancer management nationally.
