Overview
There are no other diagnostic studies associated with [disease name].
OR
[Diagnostic study] may be helpful in the diagnosis of [disease name]. Findings suggestive of/diagnostic of [disease name] include [finding 1], [finding 2], and [finding 3].
OR
Other diagnostic studies for [disease name] include [diagnostic study 1], which demonstrates [finding 1], [finding 2], and [finding 3], and [diagnostic study 2], which demonstrates [finding 1], [finding 2], and [finding 3].
Other Diagnostic Studies
Pulmonary function test:
- Spirometry in the supine and sitting positions may be helpful in the diagnosis of diaphragmatic paralysis. Findings suggestive of diaphragmatic paralysis include:
- Unilateral diaphragmatic paralysis:
- Bilateral diaphragmatic paralysis:
Maximal inspiratory pressure (MIP) :
- MIP < −80 cmH2O exclude diaphragmatic paralysis [5]
- MIP can be decreased:
- Maximal expiratory pressure (MEP) is normal.
- MEP/MIP >2 is supportive of thediagnosis of diaphragmatic paralysis.
Electromyography and physiologic testing
- Electromyography ( EMG) is not very useful in unilateral diaphragmatic paralysis.
- [Diagnostic study] may be helpful in the diagnosis of [disease name]. Findings suggestive of/diagnostic of [disease name] include:
- [Finding 1]
- [Finding 2]
- [Finding 3]
- Other diagnostic studies for [disease name] include:
- [Diagnostic study 1], which demonstrates:
- [Finding 1]
- [Finding 2]
- [Finding 3]
- [Diagnostic study 2], which demonstrates:
- [Finding 1]
- [Finding 2]
- [Finding 3]
- [Diagnostic study 1], which demonstrates:
