Incidental Acute Appendicitis on Fluorine-18-Fluorodeoxyglucose Positron Emission Tomography/Computed Tomography (18F-FDG PET/CT) Imaging: Radiology From a Different Perspective.

Although Fluorine-18-Fluorodeoxyglucose Positron Emission Tomography/Computed Tomography (18F-FDG PET/CT) is routinely used in oncological imaging, the F-18 fluorodeoxyglucose (18F-FDG) avidity is not tumor-specific. Numerous benign infective and inflammatory processes may also show increased radiotracer activity. Similarly, abnormal 18F-FDG uptake in an inflamed appendix can pose a diagnostic challenge for the interpreter of oncologic 18F-FDG PET/CT.

The hot embolus of F-fluorodeoxyglucose.

Scanning oncological patients with F-fluorodeoxyglucose (F-FDG) for their disease staging, evaluation of treatment response, and monitoring/management has become a standard of care. The use of the radioactive fluorine in the FDG molecule helps establish cell/tissue lines high on glucose consumption and hence metabolically active. Abnormalities are detected on the scan as areas of increased uptake.

Benign uptake of F-fluorodeoxyglucose in the gallbladder on positron emission tomography-computed tomography.

F-fluorodeoxyglucose (FDG) positron emission tomography (PET) has been established as the indisputable tool in the oncological arena to diagnose, stage/restage, and report treatment response for various tumor malignancies. FDG uptake mostly identifies pathological uptake in oncological scans with the tracer on PET studies; however, benign uptakes are also commonly seen. Reported here is a benign case of increased uptake of the FDG on a PET with computed tomography scan in the gallbladder (GB) of a patient being screened for a known carcinoma breast.

Simulation based medical education; teaching normal delivery on intermediate fidelity simulator to medical students.

Objective: To assess the effectiveness of medium fidelity simulator in teaching normal vaginal delivery to medical students.

Methods: The quasi-experimental study was conducted at the professional development centre of the Jinnah Sindh Medical University, Karachi, from June to December 2015, and comprised medical students. Third-year medical students were included.

Bone Turnover Markers for Osteoporosis Status Assessment at Baseline in Postmenopausal Pakistani Females.

Objective: To assess bone turnover status in osteopenic and osteoporotic postmenopausal females.

Study Design: Cross-sectional analytical study.

Place And Duration Of Study: The Aga Khan University Hospital, Karachi, from January to December 2013.

Management of Radioactive Spills in Nuclear Medicine; Teaching and Assessing with Objectively Structured Assessment of Technical Skills.

Routine work in nuclear medicine requires the careful elution of radioactivity and its subsequent, storage and handling. Though all effort is maintained to prevent any "spill" of this radioactivity, accidents are bound to happen. The response to this spill is a methodically worked out a plan that is written and adopted as a "standard operating procedure.

99mTc-Nannocolloid Localization of Lymphorenal Fistula Causing Chyluria.

Chyluria is an abnormal condition in which chyle appears in the urine because of a fistulous communication between the lymphatics and the urinary tract. It is not life-threatening and spontaneous regression is reported in 50% of cases. Lymphangiography has been the main imaging modality for localization of the site of fistula, but it is invasive and requires expertise.

Isolated tuberculous thyroiditis as solitary thyroid nodule.

Isolated involvement of the thyroid by tuberculosis is very rare as reported in literature. We are presenting a case of isolated tuberculous thyroiditis presented as a solitary thyroid nodule. The patient was treated with anti-tuberculous regimen and he responded well with disappearance of the nodule and normalization of the thyroid scan.

Extra [corrected] pulmonary uptake of Tc-99m-MAA perfusion lung scan as a result of right to left intra cardiac shunt.

Extra pulmonary accumulation of Tc-99m-macroaggregate of albumin (MAA) is rarely seen on perfusion lung scan, and has been reported in less than 4% of a study population of nearly 380 patients. It occurs when the agent bypasses the lungs due to a right to left (R-L) cardiac or pulmonary shunt, when it is shunted to the portal vein before reaching the right atrium and ventricle of the heart, and when the agent is degraded to a submicron particle size. When a pharmaceutical problem is excluded, extra-pulmonary uptake implies unusual hemodynamics with a shunt.

Sentinel lymph node scintigraphy and radioguided dissection in breast carcinoma: an initial experience at Aga Khan University Hospital.

Objective: To evaluate the efficacy of SLN biopsy using imaging and gamma probe in breast cancer and to establish this technique at Aga Khan University Hospital.

Methods: Thirty two patients (mean age 33-76 yrs) with operable breast carcinoma (4 with post-neo adjuvant therapy) with clinically negative axilla were studied. In 28 patients simultaneous axillary dissection was performed.
