What does appendicitis look like on MRI?
The normal appendix on MRI, as on CT, is visible as a blind-ending tubular structure arising from the cecum. The normal appendix may be filled with air (low T2 signal in an nondependent position) or fluid (Figure 6). Detection of a normal appendix has increased with protocol optimization and experience.
Can IBS feel like appendicitis?
It is theorized that the condition is related to the partial or intermittent obstruction of the appendix. If such a condition were to exist, it could very well masquerade as IBS.

Conclusion: MRI diagnosis of acute appendicitis can be performed without contrast for most patients; injection of contrast can be reserved for only those patients with equivocal non-contrast imaging.
Can an appendix be inflamed for months?
