A Survey of the Standard Radiation Protection Practice in Radiography Departments of Some-Selected Tertiary Hospitals in South East Nigeria
type: item
description: Section: Research Articles Keywords: Radiation, Protection, Nigeria, Radiographers Background The radiation protection practices implemented in the radiology departments of tertiary hospitals in southeastern Nigeria have a significant impact on the safety of patients, healthcare professionals, and the general public. However, there is a lack of comprehensive understanding regarding adherence to standard radiation protection protocols in these departments. Objectives This study aimed to assess the standard radiation protection practices implemented in radiography departments within selected tertiary hospitals in Southeast Nigeria. Methods The study was a prospective cross-sectional survey. These hospitals include the University of Nigeria Teaching Hospital, Ituku Ozalla (UNTH), National Orthopedic Hospital Enugu (NOHE), Nnamdi Azikiwe Teaching Hospital, Nnewi, and Federal Medical Center Abakaliki. A total of 72 radiographers working in the abovementioned hospitals were included in the study. Results The quantitative findings revealed varying degrees of compliance with standard radiation practices. While all the hospitals employed appreciable shielding measures and demonstrated knowledge of radiation safety guidelines, the quality control measures and personnel/workplace monitoring were drastically low. The research also showed that little or no work has been done by hospital management and radiographers in updating their existing knowledge, as it pertains to standard radiation protection measures. Conclusions This research thus highlights the urgency of standardized radiation protection practices within radiography departments. Recommendations include the allocation of adequate resources to ensure the availability of essential protective equipment and infrastructure and the development of comprehensive formal training programs for radiographers and other healthcare personnel involved in radiological procedures. --------------------------------------------------------…

A Case Report of a Non-Functional Ectopic Kidney in Crossed Fused Renal Ectopia on [99mTc] Tc-DMSA Renal Scintigraphy: A Rare Entity
type: item
description: Section: Case reports Keywords: Crossed fused renal ectopia, Congenital renal anomaly, Ectopic kidney, [99mTc] Tc-DMSA scintigraphy Introduction: Crossed fused renal ectopia is a rare congenital malformation, with an estimated incidence of 1 in 7,500 live births. It occurs more frequently in males and represents the second most common renal fusion anomaly after the horseshoe kidney. Case Report: Static renal scintigraphy with [⁹⁹ᵐTc]Tc-DMSA is considered the gold standard for confirming the diagnosis and ruling out the presence of a single kidney. We report the case of a 2-year-old child, born from a consanguineous marriage, followed for failure to thrive and recurrent episodes of pyelonephritis. The 99mTc-DMSA scan revealed a left pelvic ectopic kidney, fused with the right kidney at the mid-portion and upper pole. Relative renal function was almost entirely provided by the right kidney. Conclusion: Crossed fused renal ectopia is a rare congenital renal anomaly. Renal scintigraphy with [⁹⁹ᵐTc]Tc-DMSA remains the most reliable method for confirming the diagnosis and assessing renal function.

The Diagnostic Accuracy of 18F-NaF PET/CT versus 99mTc Bone Scintigraphy for Detection of Skeletal Metastases: A Systematic Review and Meta-Analysis
type: item
description: Section: Research Articles Keywords: 18F-NaF PET/CT, Bone scintigraphy, Skeletal metastases, Meta-analysis Objectives: To compare the diagnostic accuracy of 18F-sodium fluoride (NaF) PET/CT (Positron Emission Tomography/Computed Tomography) and 99mTc(Technitium-99m) bone scintigraphy for detecting skeletal metastases across malignancies using head-to-head, patient-level studies. Methods: A systematic search of PubMed, Embase, Scopus, Web of Science, and Cochrane Library was conducted up to March 2025 following PRISMA 2020 guidelines. Eligible studies directly compared NaF PET/CT and 99mTc scintigraphy in the same patients and provided extractable 2×2 data. Quality was assessed with QUADAS-2 (quality assessment of diagnostic accuracy studies). Pooled sensitivity, specificity, and diagnostic odds ratios (DORs) were calculated using a bivariate random-effects model. Narrative synthesis was performed for studies without full 2×2 tables. Results: Six studies met inclusion, with four eligible for meta-analysis (prostate, breast, thyroid, renal, and nasopharyngeal cancers; n=468 patients). Pooled sensitivity and specificity of NaF PET/CT were 0.96 (95% CI, 0.91–0.99) and 0.93 (95% CI, 0.88–0.97), respectively, compared with 0.72 (95% CI, 0.63–0.80) and 0.81 (95% CI, 0.71–0.89) for 99mTc bone scintigraphy. The pooled DOR for NaF PET/CT was 342.1 versus 23.5 for bone scintigraphy. Heterogeneity was low-to-moderate. Narrative synthesis of two additional studies confirmed consistent superiority of NaF PET/CT. Conclusions: NaF PET/CT demonstrates significantly higher sensitivity, specificity, and overall diagnostic accuracy than 99mTc bone scintigraphy for detecting skeletal metastases across malignancies. Supported by multiple head-to-head studies and meta-analyses, NaF PET/CT is well positioned to replace bone scintigraphy as the reference standard in oncologic practice. Future work should assess cost-effectiveness, multicancer prospective validation, and integration with PET…

The Ectopic Thyroid in the Anterior Mediastinum Coexisting with a Normally Positioned Thyroid Gland in Neck
type: item
description: Section: Case reports Keywords: Ectopic thyroid, anterior mediastinal mass, mediastinal thyroid Introduction: Ectopic thyroid gland is a developmental anomaly resulting from abnormal migration of thyroid tissue from its embryologic origin at the base of the tongue to its normal location in the neck. The coexistence of normally located thyroid tissue with an ectopic thyroid in the anterior mediastinum is an exceptionally rare finding. Most patients with ectopic thyroid tissue are asymptomatic; however, when the ectopic tissue enlarges, it may produce compressive symptoms, including tracheal or esophageal compression. Case presentation: We report the case of a 50-year-old woman who presented with an insidious onset of dry cough for one year which was unresponsive to conventional treatment. Imaging revealed a superior mediastinal mass along with a normally positioned thyroid gland in the neck. Initially based on imaging a provisional diagnosis of germ cell tumor vs lymphoma was made. An ultrasound guided biopsy through sternal notch was performed with histopathological examination confirming benign, enlarged thyroid tissue without evidence of malignancy. Conclusion: This case underscores the importance of considering ectopic thyroid tissue within the anterior mediastinum in the differential diagnosis of anterior mediastinal masses, which more commonly include thymic tumors, germ cell tumors, and lymphomas. ------------------------------------------------------- Introduction Ectopic thyroid is a rare but well known condition in which thyroid tissue is located at a site other than its normal anatomical location within the neck. It can be present anywhere along its path of descent from foramen cecum to anterior lower neck which may occur as a result of abnormalities in development or migration from primitive foregut to pre-tracheal region. Rarely, thyroid tissue may be found beyond this path or away from midline within the trachea, mediastinum, heart, or even the abdomen …

A Case of Ovarian NIFTP Treated with Iratherapy
type: item
description: Section: Case reports Keywords: Struma ovarii, ovarian NIFTP, iratherapy Struma ovarii is a form of mature monodermal teratoma, a rare germ cell tumor containing more than 50% thyroid tissue. Its transformation into a malignant tumor is rare. NIFTP (non-invasive follicular thyroid neoplasm with papillary nuclear features) is an entity characterized by a completely encapsulated follicular proliferation with papillary nuclear features, but without invasion or high-risk criteria. It has an excellent prognosis when located in the thyroid gland. Its presence in the struma ovarii makes its prognosis uncertain. We report a case of ovarian NIFTP treated with complementary iodine-131 isotope therapy. The patient was a 50-year-old woman who consulted for a pelvic mass appearing on pelvic ultrasound as a large, double-component, cystic and fleshy mass measuring 109×100 mm. Pelvic CT scan, performed in addition to pelvic ultrasound to better assess the characteristics of the mass, revealed a solid-cystic pelvic mass affecting the left ovary, measuring 106x117×74 mm. Left adnexectomy was indicated based on these results. The pathological examination of the surgical specimen concluded that it was a NIFTP developed on a struma ovarii. A total thyroidectomy was performed. Histology concluded lymphocytic thyroiditis against a background of multi-hetero-nodular thyroid hyperplasia, with the presence of a follicular adenoma. She underwent complementary irathérapie treatment at 1.11 GBq. The originality of this observation lies in the rarity of this histopathological entity, and the lack of international consensus on treatment opens the way for an approach aimed at codifying the classification, treatment protocol, and prognosis of ovarian NIFTPs. --------------------------------------------------------- Struma ovarii is a form of mature monodermal teratoma, a rare germ cell tumor containing more than 50% thyroid tissue [1].
