An Investigational Device (Millar Mikro-Tip Catheter) and Imaging Scan (Shear Wave Elastography) in Measuring Tumor Pressure and Stiffness in Patients With Solid Tumors Undergoing Ultrasound-Guided Biopsy

Completed · Not applicable

Conditions studied: Solid Neoplasm

In brief

This trial studies how well a Millar Mikro-tip catheter and shear wave elastography measure pressure and stiffness inside tumors among patients with solid tumors undergoing an ultrasound-guided biopsy. A Millar Mikro-tip catheter measures the pressure inside the tumor. Shear wave elastography is similar to an ultrasound and uses sound waves to vibrate the tissue in order to study tissue stiffness. These measurements may help doctors learn if pressure and stiffness are related to intratumoral fibrosis (the thickening and scarring of connective tissue).
