Table 1.

Comparison of various imaging methods.

Imaging methods Advantages Disadvantages Applications
Computerized Tomography (CT) • Painless, noninvasive and accurate • Radiation • Brain tumors.
• Blood clots and blood
• Image bone, soft tissue vessel defects. enlarged ventricles
and blood vessels all at the same time
• Not recommended for pregnant women • Abnormalities in the
nerves or muscles of the eye
• Fast and simple

Positron Emission Tomography (PET) • Double the diagnostic clarity compared to CT • Not recommended for pregnant women • Cancer
• Heart disease
• Diabetics require certain precautions. • Brain disorders
• Easy,Nondisruptive

Single-photon Emission Computed Tomography (SPET) • More available and widely used • Long scan times • Functional brain imaging
• Low-resolution and prone to artifacts and attenuation
• Functional cardiac imaging
• Less expensive than PET

Magnetic Resonance Imaging (MRI) • No radiation • Expensive • Anomalies of the brain and spinal cord
• Apparent, detailed images of soft-tissue structures compared to other imaging techniques • Cannot find all cancers
• Tumors, cysts, and other anomalies in various parts of the body
• Cannot always distinguish between malignant or benign tumors
• Breast cancer screening for women who face a high risk of breast cancer
• Injuries or abnormalities of the joints, such as the back and knee
• Certain types of heart conditions
• Diseases of the liver and other abdominal organs
• The evaluation of pelvic pain in women, with causes including fibroids and endometriosis
• Suspected uterine anomalies in women undergoing infertility evaluation
