Overview
Other imaging systems that can be used for diagnosis of systemic lupus erythematosus complications include: Fibreoptic bronchoscopy , double-contrast technique for evaluation of gastritis, scintigraphy for hepatobiliary system evaluation, bone scintigraphy and bone scans to evaluate late bone related complications.
Other Imaging Findings
- Fibreoptic bronchoscopy with bronchoalveolar lavage (BAL) and transbronchial lung biopsies:
- To substantiate the diagnosis of alveolar hemorrhage
- Upper gastrointestinal barium study:
- In patients who represent with esophagitis due to SLE
- Possible findings include:
- Mucosal granularity from reflux esophagitis
- Ulceration in severe cases
- Double contrast technique:
- In the presence of gastritis or peptic ulcers, for evaluation of stomach and duodenum
- Scintigraphy imaging:
- In the presence of acute cholecystitis symptoms
- Findings include:
- Gallbladder wall thickening
- Nonfunctioning gallbladder at hepatobiliary system
- Bone scintigraphy:
- Non specific
- May show:
- Hyperemia of the affected bone
- Osteogenesis due to avascular necrosis (AVN)
- Technetium-99m methylene diphosphonate bone scans:
- Photopenic areas will be seen primarily that will eventually progress to osteoblasts activity and increased radiotracer uptake at the margins of the infarction
- An abnormal intraosseous phlebogram may be diagnostic
- May demonstrate elevated intramedullary pressure
