X-RAY BOTH S I JOINTS AP & LAT OBL VIEW

875

An X-Ray of Both Sacroiliac (SI) joints, AP & Lateral Oblique Views, is a procedure that is used to assess the right and left sacroiliac joints that connect the sacrum, which is the base of the spine, to the iliac bones of the pelvis. It allows the proper evaluation of the spaces present in the joints and structures of the bones. It is performed to diagnose disorders like fractures, infections, and other abnormalities present in the joints.

Molecular Diagnostics and Therapy, an NABL & NABH Accredited diagnostic centre, uses advanced laboratory pathology services that also include digitalized X-Ray to obtain highly qualitative images, which is radiation-free. Our team provides reports promptly and the proper care for patients with the best treatment.

About X-Ray: Both Sacroiliac (SI) Joints AP & Lateral Oblique Views

The sacroiliac joints are essential for transferring the body's weight between the spine and the lower limbs and also provide stability to the pelvis. Some diseases affect the joints, and therefore it affects the lower back pain, buttock pain, and hip discomfort. AP and Lateral Oblique views improve the abnormalities that are not seen in a single projection. Orthopedic surgeons, rheumatologists, physiatrists, and spine specialists recommend this whole examination.

What is an X-Ray of Both Sacroiliac (SI) Joints AP & Lateral Oblique Views?

In Sacroiliac (SI) Joints AP & Lateral Oblique Views, X-Rays are taken from the front and angled lateral oblique positions so that it should be clearly visibility of the disorders present in the pelvic bones are clearly visible, and these examinations offer the best evaluation of the surfaces of joints and alignment.

Common Reasons for an X-Ray of Both Sacroiliac (SI) Joints: AP & Lateral Oblique Views

  • Evaluate chronic lower back or buttock pain
  • Diagnose sacroiliitis
  • Assess ankylosing spondylitis and other inflammatory arthritis
  • Detect osteoarthritis of the SI joints
  • Evaluate pelvic or sacral trauma
  • Detect fractures involving the sacrum or pelvis
  • Investigate joint stiffness or restricted movement
  • Assess infections involving the sacroiliac joints
  • Monitor progression of rheumatological disorders
  • Evaluate postoperative or post-treatment changes

Conditions Detected

Risks and Limitations

Safety

  • Uses a very low dose of ionizing radiation.
  • Safe when performed under appropriate clinical supervision.
  • Pregnant patients should inform the radiographer before the examination.

Limitations

  • Primarily evaluates bony structures; soft tissue abnormalities are not well visualized.
  • Early inflammatory changes may require MRI for better assessment.
  • CT or MRI should be recommended for complex fractures or detailed joint evaluation.

Conclusion

An X-Ray Both Sacroiliac (SI) joints in AP & Lateral Oblique View is a procedure to assess the sacroiliac joints and the structures of the pelvis surrounding them. It plays an essential role in diagnosing arthritis, fractures, and degenerative diseases of joints that affect the pelvis and lower spine. Molecular Diagnostics and Therapy provides advanced laboratory technologies that include advanced digitalized X-Ray imaging and offers reports promptly.
