Overview
The defintive diagnosis of mesenteric ischemia relies mainly on the imaging studies of which the most accurate is high resolution computed tomographic angiography. It demonstrates the site of occluion in the vessels as well as helps determine the choice of treatment opted.
Diagnostic Study of Choice
Gold standard/Study of choice:
- High resolution computed tomographic angiography is the gold standard test for the diagnosis of mesenteric ischemia for the following reasons:
- Determines the type of occlusion
- Identifies collateral circulation
- Potential sources of inflow
- Investigations:
- Among patients who present with clinical signs of [disease name], the [investigation name] is the most specific test for the diagnosis.
- Among patients who present with clinical signs of [disease name], the [investigation name] is the most sensitive test for diagnosis.
- Among patients who present with clinical signs of [disease name], the [investigation name] is the most efficient test for diagnosis.

Sequence of Diagnostic Studies
The [name of investigation] should be performed when:
- The patient presented with symptoms/signs 1, 2, and 3 as the first step of diagnosis.
- A positive [test] is detected in the patient, to confirm the diagnosis.
Diagnostic Criteria
- Here you should describe the details of the diagnostic criteria.
- Always mention the name of the criteria/definition you are about to list (e.g. modified Duke criteria for diagnosis of endocarditis / 3rd universal definition of MI) and cite the primary source of where this criteria/definition is found.
- Although not necessary, it is recommended that you include the criteria in a table. Make sure you always cite the source of the content and whether the table has been adapted from another source.
- Be very clear as to the number of criteria (or threshold) that needs to be met out of the total number of criteria.
- Distinguish criteria based on their nature (e.g. clinical criteria / pathological criteria/ imaging criteria) before discussing them in details.

- If relevant, add additional information that might help the reader distinguish various criteria or the evolution of criteria (e.g. original criteria vs. modified criteria).
- You may also add information about the sensitivity and specificity of the criteria, the pre-test probability, and other figures that may help the reader understand how valuable the criteria are clinically.
- [Disease name] is mainly diagnosed based on clinical presentation. There are no established criteria for the diagnosis of [disease name].
- There is no single diagnostic study of choice for [disease name], though [disease name] may be diagnosed based on [name of criteria] established by [...].
- The diagnosis of [disease name] is made when at least [number] of the following [number] diagnostic criteria are met: [criterion 1], [criterion 2], [criterion 3], and [criterion 4].
- The diagnosis of [disease name] is based on the [criteria name] criteria, which includes [criterion 1], [criterion 2], and [criterion 3].
- [Disease name] may be diagnosed at any time if one or more of the following criteria are met:
- Criteria 1
- Criteria 2
- Criteria 3
IF there are clear, established diagnostic criteria:
- The diagnosis of [disease name] is made when at least [number] of the following [number] diagnostic criteria are met: [criterion 1], [criterion 2], [criterion 3], and [criterion 4].
- The diagnosis of [disease name] is based on the [criteria name] criteria, which include [criterion 1], [criterion 2], and [criterion 3].
- The diagnosis of [disease name] is based on the [definition name] definition, which includes [criterion 1], [criterion 2], and [criterion 3].
IF there are no established diagnostic criteria:
- There are no established criteria for the diagnosis of [disease name].
