It helps to make a diagnosis without major surgery. Sometimes it all starts with a picture taken during a routine preventive examination.
During a routine X-ray, doctors found a suspicious lump in left lung. A CT scan confirmed the presence of several tumor nodules. However, bronchoscopy did not help to establish the diagnosis: the tumor was located too far from the large bronchi. In such a situation, CT-guided biopsy comes to the rescue.
During the procedure, the doctor, under the supervision of computed tomography, guides a thin needle precisely to the tumor through a small puncture in the chest and takes several millimeters of tissue for examination.
