Diagnostic Study of Choice
Study of choice
The comparison of various diagnostic studies for [disease name]
| Test | Sensitivity | Specificity |
|---|---|---|
| MRI | 43.9% | 95% |
| CT |
[Name of test with higher sensitivity and specificity] is the preferred investigation based on the sensitivity and specificity
Diagnostic results
MRI
- MRI is the imaging modality of choice for pleomorphic adenoma.[2][1]
- On T1-weighted images:
- Pleomorphic adenoma's show homogeneous intensity. [3]
- On T2-weighted images:
- On Gd-T1weighted images:
- It shows heterogeneous enhancement.[3]
Sequence of Diagnostic Studies
The various investigations must be performed in the following order:
- CT is usually the first imaging modality of choice for pleomorphic adenoma.[1]
- It helps in identifying the lesion and also helps the physician in assessing the extension of the tumor.
- MRI is the usually ordered investigation next after CT, for an even more detailed study.[1]
- It is a non-ionizing modality with excellent soft tissue distinction.
- FNA and biopsy is the definitive method of diagnosis for pleomorphic adenoma.
Name of Diagnostic Criteria
There are no established criteria for the diagnosis of pleomorphic adenoma.
