Overview
Diagnostic Study of Choice
Study of choice
1. Radiologic tests must be performed to test for asbestosis when:
- The patient has had exposure to asbestos (with Helsinki criteria indicating the dose being at least 25 fibre/ml.years.
The CT scan would show pulmonary fibrosis, pleural thickening and pleural plaques. [1] [2] 2. The best test for Silicosis is a high resolution CT: It would show widespread fibrosis with bilateral nodules and evidence of involvement of lymph nodes. It can be confirmed with lung biopsy showing acellular whorls, bi-refringent crystals of silica. [3]
Investigations:
- Among the patients who present with clinical signs of [disease name], the [investigation name] is the most specific test for the diagnosis.
- Among the patients who present with clinical signs of [disease name], the [investigation name] is the most sensitive test for diagnosis.
- Among the patients who present with clinical signs of [disease name], the [investigation name] is the most efficient test for diagnosis.
Sequence of Diagnostic Studies
The various investigations must be performed in the following order:
- [Initial investigation]
- [2nd investigation]
Diagnostic Criteria
To be qualified as a pneumoconiosis or occupational disease there must be four criteria met:
- This includes documented exposure to the particle.
- Latent period before the development of symptoms.
- Clinical signs and symptoms that entail the disease
- Exclusion of other disease modalities. [4]
