Related Imaging Modalities
Combine with CT/MRI/US for complementary detail.
CT
CT scans use X-rays to create detailed cross-sectional images of the body. They are particularly useful for detecting bone fractures, tumors, and internal bleeding.
MRI
MRI uses powerful magnets and radio waves to produce detailed images of organs and soft tissues. Excellent for brain, spine, and joint imaging.
Ultrasound
Ultrasound uses sound waves to create real-time images. Commonly used for pregnancy monitoring and examining organs like the heart, liver, and kidneys.

Brain Tumor PET-MRI
FDG or amino acid tracers (e.g., methionine, FDOPA) show tumor metabolism. MRI provides detailed anatomical information with contrast enhancement, edema, and mass effect. Tumor shows increased tracer uptake with variable enhancement patterns.
Pediatric Malignancy PET-MRI
FDG-avid or specific tracer-avid lesions in primary tumor and metastatic sites. MRI provides superior soft tissue contrast for local tumor extent. PET shows metabolic activity for whole-body assessment.
Pelvic Malignancy PET-MRI
FDG-avid or specific tracer-avid lesions (e.g., PSMA for prostate) with MRI providing superior soft tissue contrast. Tumor shows restricted diffusion on DWI, enhances with contrast, and demonstrates increased metabolic activity on PET.
