Abstract: A 46-year-old man with papillary thyroid cancer post total thyroidectomy was referred for post radioiodine (131I) whole-body scan. Whole-body images revealed intense 131I uptake in the bed thyroid and a focal abnormal uptake in the testicular area. Subsequent SPECT/CT demonstrated that the focal uptake corresponded to the left epididymis, and the pathology report revealed a spermatocele with no immunohistochemical features for thyroid tissue. Many cases of unexpected radioiodine uptake have been reported, and spermatocele could be counted for another possibility of incidental 131I uptake despite an unclear mechanism.

AbstractBackgroundImage-based measurement of absorbed dose of Ra-223 dichloride may be useful in predicting therapeutic outcome in patients with castration-resistant prostate cancer (CRPC). In general, SPECT has been found to be more accurate than planar imaging in terms of lesion-based analysis. The aims of this study were to assess the feasibility and clinical usefulness of Ra-223 SPECT.The energy spectrum of Ra-223 and SPECT images of a cylindrical phantom with a hot rod were obtained to determine the collimator candidates and energy window settings suitable for clinical Ra-223 SPECT (basic study A). Another phantom wit...

Rationale: The spine is the most common site of bone metastases due to thyroid cancer; however, spinal cord compression as a complication of metastatic thyroid cancer is very rare. Patient concerns: A 48-year-old female patient was presented to the Neurosurgical Department, complaining of progressive back neck pain with bilateral upper extremities numbness and weakness for 4 months. Diagnosis: Imaging studies revealed osteolytic destruction in bodies and accessories of the second and third cervical vertebrae with a huge soft-tissue mass compressing spinal cord and causing swelling. After the neurosurgical decompression s...

Eid Mubarak!It seems surreal that two weeks have passed so quickly. As today is the holiday of Eid Al-Adha, the hospital has very little activity, and I'm taking the day to pack, catch up on correspondence, and perhaps pay one last visit to Slipway for lunch.This was on Page 16 of the local English-language newspaper a few days ago. A coincidence with my arrival in country? I wonder...I haven't posted since heading out to Ngorongoro Crater, so let me briefly fill you in on that incredible experience. I'll place some photos here, but they can all be found at THIS LINK for your leisurely perusal. I left Dar in...

I just completed (a rather long) Day 4 at Aga Khan Hospital, here in Dar es Salaam, Tanzania (in case you didn't know where I was). As usual, time flies when you're having fun, and I really am enjoying my time here.Today was a day of many hats. In the morning, I played " real doctor " and attended an OB Gyn lecture series beamed over from the Aga Khan University Hospital in Nairobi:The full title was " Female Sexual Dysfunction and its Effects upon Fertility " and it was quite well done. While the lecture will have little impact upon my medical practice, I'm trying to get the staff used to me hanging ar...

Conclusion SPECT imaging of the skull is a very beneficial complementary form of investigation in patients with craniofacial malignancies for the assessment of osseous invasion, particularly in tumors likely to invade the skull base.

CONCLUSION: Whole-body SPECT/CT is the optimal modality of choice for metastatic workup, including detection of extra-axial lesions, with improved sensitivity and similar specificity compared to targeted SPECT/CT. PMID: 28812019 [PubMed - in process]

This study compared68Gallium-prostate-specific-membrane-antigen based Positron-emission-tomography (68Ga-PSMA-PET) and99metastabletechnetium-3,3-diphospho-1,2-propanedicarbonacid (99mTc-DPD-SPECT) in performing skeletal staging in prostate cancer (PC) patients and evaluated the additional value of the information from low-dose-computed tomography (CT).Materials and MethodsIn this retrospective study, 54 patients who received68Ga-PSMA-PET/CT and99mTc-DPD-SPECT/CT within 80 days were extracted from our database. Osseous lesions were classified as benign, malignant or equivocal. Lesion, region and patient based analysis was p...

Conclusions: These findings demonstrate the theranostic potential of [(131)I]SGMIB-2Rs15d. An initial scan using low radioactive [*I]SGMIB-2Rs15d allows patient selection and dosimetry calculations for subsequent therapeutic [(131)I]SGMIB-2Rs15d, and could thereby impact therapy outcome on HER2(+) BC patients.

Abstract CLINICAL/METHODICAL ISSUE: In the last few years nuclear medical diagnostics have experienced a unprecedented renaissance in the diagnostics of prostate cancer, due to the availability of hybrid imaging with positron emission tomography computed tomography (PET/CT), PET magnetic resonance imaging (PET/MRI) and single photon emission computed tomography (SPECT) CT as well as the development of prostate-specific radiopharmaceuticals. METHODICAL INNOVATIONS: The use of fluorodeoxyglucose (FDG), which has been successfully implemented for many years in PET diagnostics, is only helpful in dedifferent...
