Mri of the hip joint

Article by Dr. CKII. Kong Tien Dat – Department of Diagnostic Imaging – Share99 Ha Long International Health Hub.

Magnetic Resonance Imaging (MRI) is considered one of the revolutionary inventions in medical engineering. Hip magnetic resonance imaging has a wide range of applications and is safe, not causing radiation to the patient.

Mri resonance imaging is one of the most modern imaging techniques in medicine using fields and radio waves. Mri resonance imaging techniques provide high-contrast images, good anotomical details that allow accurate detection of er erm lesions, the structure of parts of the body to be examined. In particular, the ability to reproduce 3D images is good, there are no side effects, so it is increasingly widely prescribed for many different specialized applications.

Hip joints are joints with complex structure and functions, diseases related to the joint including injuries, bone damage, necrosis of the joints, arthritis, osteoarthritis, tumors … There are many photo surveys for hip diseases. X-rays are usually the first introsenter. Computer-class scans are valuable for detailed evaluation of bone structure, bone shell, but hip resonance imaging plays a particularly important role in evaluatiing the software structures that make up the hip joints such as: articular sacks, articular cartilage, muscles involved in hip movement, bone marrow ….

Hip resonance is inlet for the following diseases:

• Femoral necrosis
• Cartilage damage in hip osteoarthritis
• Fractures difficult to detect on X-rays
• Bone tumours: Including benign bone tumours and bone cancer
• Bone marrow damage
• Arthritis and synapses
• Bone and soft damage around the joints
• Nerve compression

3.1 Aseptic necrosis of the femoral crown

More common in adults and men, in clinical contexts such as post-traumatic stress disorder, long-term steroid therapy, alcoholism, obesity, pancreatitis…

Hip resonance imaging is the best technique today to reveal lesions in this pathology, which can be revealed at a very early stage when clinical symptoms are atypical. Common images are changes in the bone marrow area in the crown, subsidence of articular cartilage, bone subsidence, continuous loss of articular cartilage, flattening, deformation of the femoral crown …

3.2 Osteochondrosis

The disease encountered in middle and elderly people presenting with osteochondrosis includes: Pain, limiting movement of the hip joint such as contraction, folding, form, closing, turning inside, rotating outside;

The resonance of the hip joint clearly reveals lesions in this pathology such as: Stenosis of the joints, bone fibers under cartilage, bone spikes, cyst formation, joint effusion …

3.3 Infectious hip arthritis

The hip joint may experience infectious inflammation, bloodstream germs, adjacent inflammatory drives, or lesions that directly enter the hip joint… causes damage to bones, cartilage, active sacks, surrounding software

The resonance of words is a technique that should be chosen for early detection, clear lesion disclosure, related evaluation with the surrounding components.

3.4 Fracture of the hip area

Appears after the injury with a bump on the hip, thigh area. The resonance allows better evaluation of hard-to-detect fracture lines on Xquang, less deviated fractures, further evaluation of possible complications such as femoral necrosis, nerve compression …

3.5 Legg – Calve – Perthes

As a pathology in children, common at the age of 4-7 years, male superiority. The disease is characterized by hip pain that is not caused by injury, the child goes to practice due to pain and is increasingly difficult to walk.

Hip resonance imaging helps to assess edicts and signal changes at an early stage when Xquang is not yet present.

3.6 Hip dysarthritis

The disease is common in children. Meet more females than men. Met on both sides about 33%. Risk factors include: family history, reverse laying, scoliosis, structural abnormalities around the joints. Signs that depend on the age of the person: In babies with one leg longer than the other, in children older than one side will be less flexible or the child walks limply, In adolescents or young adults, the first signs may be noticed as hip pain or limping walks.

Hip resonance imaging evaluates this pathology well as clearly revealing the shape of the articular cartilage, which allows to better locate the head of the femur, associated with the mortar drive better. The word resonance also shows accompanying complications such as anemia necrosis, joint effulation …

3.7 Sliding head on femur (dislocated hip)

As a child's disease, risk factors include: Obesity, trauma, end endiormonal abnormalities … The expression of the image is a deviation from the back – under the head on the femur.

The resymable allows to assess the shape of articular cartilage, cartilage growth, head deviations on the femur, relation of the femur head to the mortar, related complications such as necrosis of the crown.

3.8 Torn cartilage

Common after traumatic illness. Normal border cartilage has a triangular shape. Signs of cartilage tearing are increased signals in cartilage or continuous cartilage loss. Hip resonance imaging is by far the best imaging technique to reveal this lesion.

MRI is a non-invasive imaging medium so it generally does not cause any harm to the patient's body. However, before conducting a hip resonance imaging, it is necessary to screen the patient for not violating the contraintifications, namely:

• Patients with cardiovascular devices permanently placed in the body such as pacemakers, defibrillators, artificial heart valves … or there are metal fragments, metal implants in the body such as shrapnel, vascular clamps, hearing aids, automatic sub-skin drug pumps …
• People with psychological syndrome are afraid of enclosed spaces.
• People may be severely obese, their size or body weight too large to fit in the cage.
• Patients do not need to fast, get simple costumes, do not bring anything on them and arrange to lie right on the plane of the machine, slowly put in the cage.

Meanwhile, patients have access to headphones, which both help reduce noise and are a means of communication with external technicians; at the same time, help the patient to be mentally comfortable. After ensuring the quality of the hip image to be collected technically, the plane is removed from the cage and the patient can sit up, completely living as usual. However, there should be a room to monitor the patient for 15 minutes before leaving, to avoid reactions, abnormal manifestations and can be supported, intervened in a timely manner.

Hip resonance imaging (MRI) is a technique that requires advanced medical equipment along with a team of highly specialized and experienced doctors. Therefore, to get the best diagnosis and treatment, you should choose the leading medical centers in our country. Currently, the Department of Diagnostic Imaging is one of the spearheads of Share99 International Health Hub equipped with the most modern and advanced equipment in the country as well as in the region. The faculty has 6 ultrasound rooms, 4 DR X-ray rooms (1 full-axis camera, 1 light-up machine, 1 synthesizer and 1 mammogram), 2 DR portable X-ray machines, 2 multi-range commectomy rooms (1 128-range and 1 16-sequence machine), 2 Resonance Imaging rooms (1 Tesla 3 and 1.5 Tesla) , 1 interventional an anethortic room with 2 interfaces and 1 bone mineral density measurement room. The doctors at the Faculty are well-trained at home and abroad. Especially when coming to Share99 International Health Hub, patients do not need to wait long, quick examination time and are carefully guided by experienced medical staff to use drugs, guide lifestyle changes in a positive way to help patients easily comply with their disease management.
