Which modality provides mucosal visualization and tissue biopsies for histopathology?

• A. Endoscopy
• B. Ultrasound
• C. CT
• D. MRI

Answer: (A)

Direct visualization of the mucosal lining with the ability to obtain tissue samples for histopathology is provided by endoscopy. A flexible endoscope lets you inspect the mucosa of the esophagus, stomach, colon, and other accessible areas, and small biopsy forceps enable targeted tissue samples that are then examined under a microscope to make a diagnosis. Imaging methods like ultrasound, CT, or MRI visualize structures noninvasively and show anatomy and pathology, but they do not collect mucosal biopsy samples for histopathology (though they may guide procedures).
