F-18 fluorodeoxyglucose positron emission tomography/computed tomography in conjunctival melanoma with recurrence.

Ocular melanoma is classified under the category of noncutaneous melanomas. Noncutaneous melanomas are relatively rare. Ocular melanoma commonly arises from choroid.

Hematoma in Urinary Bladder Masquerading as Neoplastic Mass.

The most common reason for intraluminal urinary bladder hematoma is trauma. However in gynecological and pelvic malignancies, the pelvic irradiation can affect non targeted organs resulting in urogenital complications like hematoma. Small size hematoma can be easily diagnosed in ultrasound.

Role of Tc MDP Bone Scan in Delineation of Ischaemic Zone in Cases of Severe Frostbite.

Frostbite or cold burn is the medical condition in which localized damage is caused to exposed skin and subcutaneous tissue due to freezing. Frostbite most likely involves body parts farthest from the heart and those with large exposed areas. At or below 0 °C (32 °F), blood vessels close to the skin start to constrict, and blood is shunted away from the extremities via the physiological feedback action of glomus bodies.

Comparative study of (18)F-DOPA, (13)N-Ammonia and F18-FDG PET/CT in primary brain tumors.

Aim: To determine the diagnostic reliability of (18)F-FDOPA, (13)N-Ammonia and F18-FDG PET/CT in primary brain tumors. We evaluated the amino acid and glucose metabolism of brain tumors by using PET with (18)F-FDOPA, (13)N-Ammonia and F18-FDG PET/CT.

Materials And Methods: Nine patients undergoing evaluation for brain tumors were studied.
