Free-hand Ultrasound plays an important role in thyroid diagnostics as a real-time examination, not ionizing and non-invasive, cost effective, ideal also for repetitive followup and able to give information about anatomy, hemodynamics and tissue stiffness, i.e. Elastosonography.
To assess retrospectively if nephrostomy guided by ultrasound (US) and electromagnetic needle tracking was feasible in mild to moderate hydronephrosis.
Patient presented with pancreatitis. Using Volume Navigation on the LOGIQ E9, (GE Healthcare), image fusion using CT and ultrasound data sets was possible. eTRAX Needle Tip Tracking (CIVCO Medical Solutions) was useful for continuous visualization of the needle tip.
An 86 year-old-male with a history of metastatic colon cancer to the liver underwent multiple courses of chemotherapy over a period of three years. His disease was under control except for one metastasis in the dome of the liver. Despite multiple courses of chemotherapy, this hepatic lesion persisted. His oncologist exhausted all possible treatment options of chemotherapy and feared further toxicity, and unlikely benefit from further treatments.
A 62 year-old woman affected by systemic lupus erythematosus since she was 37, and taking corticosteriods, underwent abdominal ultrasound for a mild elevation of transaminases. A 30mm hypoechoic and irregular mass was detected in segment II-III and a biopsy of the mass was performed.
