pleural

Diagnosis of Mesothelioma is usually confirmed with clinical findings and a careful assessment of tissue biopsy and radiological. Reviews patient's medical history, was also a history of exposure to asbestos, with a complete physical examination, chest X-ray or abdomen and lung function tests. CT or MRI may be performed at this time. If one of the first tests prove suspicious for mesothelioma, a biopsy is needed to confirm thisDiagnosis.

Imaging techniques and their value in the diagnosis and assessment of mesothelioma

There are various imaging techniques that can be useful when malignant pleural mesothelioma, combining history with exposure to asbestos or suspected secondary activity. While imaging techniques can be useful in assessing the risk of cancer, the final diagnosis is still most often established through the diagnosis of fluid or tissue sample.

Some of the most frequentimaging techniques used are:

X-ray

Chest X-ray can reveal pleural effusion (fluid accumulation), the restriction is to the right lung (60%) or left (40%). On this occasion, the mass can be. The signs of the disease, non-cancerous asbestos, such as pleural plaques or pleural calcification, or scarring due to asbestosis may also be noted.

Computed tomography (CT)

CT can also define pleural effusion,and pleural calcification, thickening of interlobular crack pleural thickening, or possible chest wall invasion. CT, but can not distinguish between changes in relation to asbestos disease mesothelioma benign verse (pleural disease), or differentiate adenocarcinoma of the lung to the pleura, which can spread. CT can also guide precious fine-needle aspiration of the masses for the diagnosis of pleural tissue.

Magnetic Resonance(RM)

MRI scans are used most often to determine the size of the tumor prior to aggressive treatment. Because they provide multiple images in the plane, are better able to identify tumors in contrast to the normal structure. They are also more accurate than CT in assessing enlargement of mediastinal lymph nodes (lymph nodes are located between the two lungs), and the area of the membrane is clear, both to play an important role in surgical candidacy.
