Necrotizing granuloma of the lung: imaging characteristics and imaging-guided diagnosis
Rennae Thiessen1, Jean M Seely, Frederick R K Matzinger
1Department of Diagnostic Imaging, The Ottawa Hospital, 1053 Carling Ave., Ottawa, ON K1Y 4E9, Canada.
Objective:
The purpose of this study was to assess CT findings and the sensitivities of imaging-guided fine-needle aspiration (FNA) biopsy and core needle biopsy in the diagnosis of necrotizing granuloma of the lung.
Conclusions:
The CT characteristics of necrotizing granuloma are indistinguishable from those of malignant tumors; tissue diagnosis therefore is necessary. Core needle biopsy is a sensitive method for diagnosing necrotizing granuloma of the lung, but FNA biopsy is insufficient for diagnosis.

Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...
