What is a Plantar Fasciitis MRI?

When it comes to imaging the foot, there are a few different options available, such as MRI scans and plain film x-rays. It’s important to understand the key differences between these two procedures. The cost of these imaging tests can vary depending on the specific procedure and your insurance coverage. To find out if there are any discounts available or if you’re covered, it’s recommended to consult with your doctor. In general, getting the imaging done at your doctor’s office is typically less expensive compared to going to a hospital. The most cost-effective imaging methods for foot-related issues include ultrasound, x-rays, and MRI scans.


One effective way to assess the thickness of the plantar fascia is by using a high-resolution ultrasound. This non-invasive procedure is capable of detecting changes in the thickness of the plantar fascia, including areas of thickening. This is particularly relevant for people who engage in activities like running and walking, as they are more prone to developing plantar fasciitis. Another diagnostic tool that can be utilized to analyze the thickness of the plantar fascia is magnetic resonance imaging (MRI). The MRI offers several advantages when it comes to identifying the causes of plantar fasciitis. By employing any of these methods, medical professionals can accurately diagnose and determine the underlying factors contributing to plantar fasciitis.

A thorough diagnostic examination can provide a detailed analysis of the plantar fascia and the medial calcaneal nerve, both of which are closely linked and can potentially cause nerve pain. To assist with visualization, the following table displays common MRI findings related to this condition. The findings are arranged in ascending order of severity. Additionally, the table below summarizes the primary observations associated with plantar fascia ruptures. Frequently, abnormalities are detected at the site of the rupture, which are indicative of plantar fasciitis.

MRI is the standard diagnostic test for diagnosing Plantar Fasciitis. However, ultrasound is also an important diagnostic tool. Although it’s not as precise as MRI, it’s comparable to MRI and is still useful in confirming a clinical diagnosis of plantar fasciitis. In these cases, MRI may be used only when ultrasound is inconclusive or when the patient’s symptoms are difficult to explain.

The MRI is the preferred imaging modality for evaluating the extent of damage in the plantar fascia. Sonography is the initial imaging modality for this condition, but MRI is recommended for more complicated pathologies. The researchers conducted this study in the Radio diagnosis Department of Zagazig University Hospitals. The study included 21 patients with plantar fasciitis and five asymptomatic volunteers as control subjects. All patients underwent an MRI and ultrasonography. MRI showed that the plantar fascia was thickened in the symptomatic feet, while ultrasound revealed that the plantar fascia was normal.

MRI is an imaging tool that provides detailed cross-section images of the bones and tendons in the foot and ankle. The process of undergoing an MRI takes about 30-60 minutes. The patient must be still during the process. The MRI scanner produces noise during the entire procedure, which can be distracting to the patient. Patients should not undergo MRI if they have a pacemaker, metal screws, or tattoos.

Plain film x-ray

A plain film x-ray of the plantar fascia is nonspecific and is not always necessary for the diagnosis of plantar fasciitis. Plantar fascia disorders are often associated with heel pain, which is not a diagnosis of rheumatoid arthritis. Common sonographic features of plantar fasciitis include thickening of the PF, loss of fibrillar structure, perifascial collections, calcifications, and hyperemia. Plain film x-rays can also show oedema of the surrounding soft tissues and abnormalities of the deep fat pad.

A plain film x-ray for plantar fasciatis can also reveal indirect signs of the condition, such as pathological changes of the bone. Radiographs may show lytic lesions or radiopaque foreign material. These changes may indicate infectious fasciitis or osteomyelitis. Infections of the plantar fascia may also lead to changes in the bone morphology and/or periosteal thickening. A stress fracture can also accompany plantar fasciitis.

Radiographic findings of plantar fasciitis vary significantly. The medial and central plantar fascia are affected most frequently, although the proximal plantar fascia may also be involved. Plain film x-ray findings are generally normal, except for the presence of multiple nodular areas of thickening in the inferior and middle parts of the plantar fascia. Larger lesions may show evidence of plantar musculature infiltration.

One study used a plain film x-ray to measure the thickness of the plantar fascia on a lateral non-weight-bearing radiograph. The study applied a blinding technique to the image assessor, which resulted in a statistically significant difference between the two groups. The CPHP participants were 2.4 mm thicker than those with non-CPHP.

Nonsurgical treatment for plantar fasciitis typically involves stretching the plantar fascia and using arch supports to stabilize the heel. Conservative treatment includes rest, padded shoes, orthotics, and heel lifts. Anti-inflammatory medications are usually prescribed to alleviate symptoms. In some cases, surgery may be necessary. However, nonsurgical care is often the best treatment for acute heel pain. If nonsurgical care does not relieve symptoms, surgery is often the only option.
