The video discusses the challenges in diagnosing medical conditions, particularly cancer, and introduces PET CT technology as a solution. PET CT combines positron emission tomography and computer tomography to provide highly accurate diagnostic images. It highlights the process where glucose with radioactive markers is used to identify cancerous cells, which metabolize glucose faster than normal cells. The video explains how PET CT benefits tumor patients by accurately locating tumors and monitoring therapy effectiveness. It also mentions the broader applications of PET CT in cardiology and neurology, marking a significant advancement in whole-body diagnosis.

In what ways can PET CT technology assist in monitoring ongoing therapy for patients?
