Capsule Endoscopy MCQS-Quiz-Test
Capsule Endoscopy MCQS-Quiz-Test
Capsule endoscopy, a novel diagnostic modality has emerged from the innovative work of Professor Paul Swain at the Royal London Hospital in the UK. This procedure is revolutionizing gastrointestinal imaging. This procedure employs a small ingestible capsule equipped with optical components, light-emitting diodes, and a transmitter. As the capsule traverses the digestive system, it captures video images, transmitted via digital radiofrequency communication to a portable recorder worn outside the body of the patient. Essential components include the workstation, a modified personal computer facilitating off-line data storage and image analysis. With remarkable diagnostic yield, capsule endoscopy proves particularly valuable in detecting cryptic bleeding and diagnosing small bowel Crohn’s disease, though careful consideration of contraindications and advancements in technology continually enhance its capabilities.
Here is the MCQs test on Capsule Endoscopy MCQS as quiz or test. These MCQs are prepared to fulfil the requirement for all types of medical exams as NEET, USMLE, PLAB, Promatric and ALL TYPES OF MEDICAL BOARD Exams all over the world.
