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 |
