CT pelvis: Definition, Uses, and Clinical Overview

CT pelvis is a type of medical imaging that creates detailed cross-sectional pictures of the pelvis using X-rays and computer processing. It is commonly used in emergency care, orthopedics, and general medicine to evaluate bones, joints, and nearby organs. A CT pelvis can be performed with or without IV contrast, depending on the clinical question. The goal is to help clinicians see structures that may not be clear on a standard X-ray.

CT hip: Definition, Uses, and Clinical Overview

CT hip is a computed tomography (CT) scan focused on the hip joint and nearby bones and soft tissues. It uses X-rays and computer processing to create detailed cross-sectional images. It is commonly used in emergency care, orthopedics, and preoperative planning to evaluate hip pain or injury. It may be performed with or without intravenous (IV) contrast, depending on the clinical question.

CT arthrogram hip: Definition, Uses, and Clinical Overview

CT arthrogram hip is a CT scan of the hip performed after contrast dye is placed directly into the hip joint. It is designed to outline the inside of the joint so small tears or defects are easier to see. It is commonly used in orthopedics and sports medicine when hip pain suggests labrum or cartilage injury. It is also used when MRI is not possible or when CT detail is preferred.

CT acetabulum: Definition, Uses, and Clinical Overview

CT acetabulum refers to a CT scan focused on the acetabulum, the cup-shaped socket of the hip joint. CT stands for computed tomography, an imaging method that uses X-rays to create detailed cross-sectional pictures. It is commonly used to evaluate hip socket bone anatomy, fractures, and surgical planning. It may also be used after surgery to assess hardware position or bone healing.

Cross-table lateral view: Definition, Uses, and Clinical Overview

Cross-table lateral view is an X-ray view that shows the hip from the side. It is taken with the X-ray beam passing “across” the table while you lie down. It is commonly used in emergency, trauma, and orthopedic settings. It helps clinicians evaluate hip alignment, fractures, and joint shape when standard views are limited.

Cross-table lateral: Definition, Uses, and Clinical Overview

Cross-table lateral is a specific X-ray view that shows the hip (or upper femur) from the side. It is commonly used when a person cannot safely move the painful leg into other positions. It is frequently ordered in emergency and trauma settings and after hip surgery. It helps clinicians assess alignment, fractures, and hip joint positioning on a lateral projection.

Cross-over sign present: Definition, Uses, and Clinical Overview

Cross-over sign present is a radiology description seen on a standard X-ray view of the pelvis and hip. It refers to a specific line pattern that can suggest the hip socket (acetabulum) faces slightly backward rather than forward. Clinicians most often mention it when evaluating hip pain and possible femoroacetabular impingement (FAI). It is a sign on imaging, not a diagnosis by itself.

Cross-over sign: Definition, Uses, and Clinical Overview

Cross-over sign is a finding seen on a standard front-view pelvic X-ray. It suggests that the hip socket (acetabulum) may be rotated in a way called acetabular retroversion. Clinicians use it most often when evaluating femoroacetabular impingement (FAI) and certain causes of hip pain. It is a radiographic sign, not a diagnosis by itself.

C-reactive protein: Definition, Uses, and Clinical Overview

C-reactive protein is a substance made mainly by the liver that rises in the blood when there is inflammation in the body. It is measured with a simple blood test. Clinicians use it as a general signal that the immune system is “active,” not as a diagnosis by itself. In orthopedics, it is commonly used when evaluating possible infection or inflammatory causes of hip and joint symptoms.
