❓ Frequently Asked Questions
What is advanced diagnostics and imaging?
It refers to using high-tech tools to detect, monitor, and evaluate medical conditions, giving detailed images and data from modalities like MRI, CT, ultrasound, and PET to aid diagnosis.
How do MRI and CT scans differ?
MRI uses magnetic fields and radio waves to image soft tissues without ionizing radiation, while CT uses X-rays to create quick cross-sectional images, often excelling in bone and trauma assessments.
What is ultrasound used for in diagnostics?
Ultrasound uses high-frequency sound waves to produce real-time images of organs and tissues, and is common for pregnancy, abdominal checks, heart function, and guiding procedures—without radiation.
What is PET scanning and when is it used?
PET scanning detects metabolic activity using radioactive tracers, often combined with CT or MRI to localize activity; it is frequently used for cancer evaluation, brain disorders, and heart conditions.
Are these imaging techniques safe, and what should be considered?
Most are safe but involve different risks: CT and PET expose radiation; MRI has metal-related safety considerations; contrast agents can cause allergies or kidney issues. Always follow clinician guidance and facility safety protocols.
