Bone scintigraphy in chronic knee pain: comparison with magnetic resonance imaging

Article Abstract:

Bone scintigraphy may effectively identify inflammatory changes to the cartilage in painful knees, but is less effective than magnetic resonance imaging at identifying cartilage defects or osteophyte formation. Bone scintigraphy is a scanning technique that identifies increased uptake of a radioactive tracer in bones that may be undergoing abnormal changes. Researchers compared the diagnostic imaging techniques in 58 people with chronically painful knees. Bone scanning results compared favorably with magnetic resonance images of knees with changes in the bone below the cartilage. Bony overgrowth and cartilage damage were better detected by magnetic resonance imaging.

Correlation between radiographically diagnosed osteophytes and magnetic resonance detected cartilage defects in the patellofemoral joint

Article Abstract:

Magnetic resonance imaging (MRI) may be able to detect the early signs of osteoarthritis in the knee. Researchers compared cartilage defects in the knee identified by MRI with cartilage defects identified by X-rays in 57 people with chronic knee pain. In most cases, MRI confirmed cartilage damage seen on X-ray. Cartilage damage was also strongly associated with knee pain. Many researchers believe cartilage damage precedes the narrowing of the joint.

Correlation between radiographically diagnosed osteophytes and magnetic resonance detected cartilage defects in the tibiofemoral joint

Article Abstract:

Magnetic resonance imaging (MRI) may be able to detect the early signs of osteoarthritis in the knee. Researchers compared cartilage defects in the knee identified by MRI with cartilage defects identified by X-rays in 59 people with chronic knee pain. In most cases, MRI confirmed cartilage damage seen on X-ray. Cartilage damage was also strongly associated with knee pain. Many researchers believe cartilage damage precedes the narrowing of the joint.
