In addition, the presence of B symptoms (one or more of the following: unintentional loss of 10% body weight in the last 6 months, night sweats, or persistent fever of 38 °C or more) or their absence is expressed with B or A, respectively. [45] CT scan or PET scan imaging modalities are used to stage cancer
Stage IV: The lymphoma is in one or more organs beyond the lymphatic system, such as the liver, lungs, bone marrow, or cerebrospinal fluid. [2] A patient's stage may be determined through blood tests, bone marrow biopsy, chest X-rays, computed tomography (CT) scans, positron emission tomography (PET) scans, and magnetic resonance imaging (MRI).
The stage depends on both the place where the malignant tissue is located (as located with biopsy, CT scanning, gallium scan and increasingly positron emission tomography) and on systemic symptoms due to the lymphoma ("B symptoms": night sweats, weight loss of >10% or fevers).
Modern detail-oriented scans such as high-resolution computed tomography (HRCT) is the gold standard in respiratory medicine and thoracic surgery for investigating disorders of the lung parenchyma . Contrasted CT scans of the chest are usually used to confirm diagnosis of for lung cancer and abscesses , as well as to assess lymph node status at ...
In radiology, the tree-in-bud sign is a finding on a CT scan that indicates some degree of airway obstruction. [1] The tree-in-bud sign is a nonspecific imaging finding that implies impaction within bronchioles, the smallest airway passages in the lung.
Non-Hodgkin lymphoma (NHL), also known as non-Hodgkin's lymphoma, is a group of blood cancers that includes all types of lymphomas except Hodgkin lymphomas. [1] Symptoms include enlarged lymph nodes, fever, night sweats, weight loss, and tiredness. [1] Other symptoms may include bone pain, chest pain, or itchiness. [1]
A CXR of a person with lung cancer, which was causing superior vena cava syndrome A CT image showing compression of the right hilar structures by cancer. The main techniques of diagnosing SVCS are with chest X-rays (CXR), CT scans, transbronchial needle aspiration at bronchoscopy and mediastinoscopy. [6]
The diagnosis of lung cancer is based on chest radiograph and computed tomography (CT) scans, and is confirmed by biopsy. Biopsy is usually performed via bronchoscopy or CT-guided biopsy. Treatment and prognosis depend upon the histological type of cancer, the stage, and the patient's performance status. Treatments include surgery, chemotherapy ...
