RADIOLOGY: ABDOMEN: Case# 33664: OSSEOUS METASTASES TO THE RIGHT HIP. A 56 year old gentleman with upper abdominal pain and an ultrasound of the gallbladder that demonstrated a thickened wall with distension. The patient was injected with 20 mCi of Tc-99m HDP. After allowing 2 hours for blood pool activity to clear, whole body imaging with magnified views demonstrated increased osseous remodeling in the subcapital region of the right. The sensitivity of bone scans to detect a recent osseous metastases exceeds that of x-ray. Whole body imaging permits an entire skeletal survey for clinically occult metastases. Early detection of metastasis can allow early intervention e.g. irradiation and thus avert a crippling fracture. Patient Prep: No oral contrast (attenuation) study should be done prior to the bone scan.
