Editing Plantar fasciitis (section)

===Imaging===
Medical imaging is not routinely needed. It is expensive and does not typically change how plantar fasciitis is managed.<ref name="Yin_2014">{{cite journal | vauthors = Yin MC, Ye J, Yao M, Cui XJ, Xia Y, Shen QX, Tong ZY, Wu XQ, Ma JM, Mo W | display-authors = 6 | title = Is extracorporeal shock wave therapy clinical efficacy for relief of chronic, recalcitrant plantar fasciitis?

The plantar fascia has three fascicles-the central fascicle being the thickest at 4&nbsp;mm, the [[lateral (anatomy)|lateral]] fascicle at 2&nbsp;mm, and the [[medial (anatomy)|medial]] less than a millimeter thick.<ref>{{cite journal | vauthors = Ehrmann C, Maier M, Mengiardi B, Pfirrmann CW, Sutter R | title = Calcaneal attachment of the plantar fascia: MR findings in asymptomatic volunteers | journal = Radiology | volume = 272 | issue = 3 | pages = 807–814 | date = September 2014 | pmid = 24814176 | doi = 10.1148/radiol.14131410 }}</ref> In theory, plantar fasciitis becomes more likely as the plantar fascia's thickness at the calcaneal insertion increases. A thickness of more than 4.5&nbsp;mm [[ultrasound]] and 4&nbsp;mm on [[magnetic resonance imaging|MRI]] are useful for diagnosis.<ref>{{cite journal | vauthors = League AC | title = Current concepts review: plantar fasciitis | journal = Foot & Ankle International | volume = 29 | issue = 3 | pages = 358–366 | date = March 2008 | pmid = 18348838 | doi = 10.3113/fai.2008.0358 | s2cid = 6734497 }}</ref> Other imaging findings, such as thickening of the plantar aponeurosis, are nonspecific and have limited usefulness in diagnosing plantar fasciitis.<ref name="Orchard_2012"/>

[[Bone scan|Three-phase bone scan]] is a sensitive modality to detect active plantar fasciitis. Furthermore, a [[bone scan|3-phase bone scan]] can be used to monitor response to therapy, as demonstrated by decreased uptake after corticosteroid injections.<ref>{{cite journal | vauthors = Pelletier-Galarneau M, Martineau P, Gaudreault M, Pham X | title = Review of running injuries of the foot and ankle: clinical presentation and SPECT-CT imaging patterns | journal = American Journal of Nuclear Medicine and Molecular Imaging | volume = 5 | issue = 4 | pages = 305–316 | year = 2015 | pmid = 26269770 | pmc = 4529586 }}</ref>
