Other imaging tools used to assess the size and spread of a phyllodes tumor include ultrasound and magnetic resonance imaging (MRI). [11] None of these imaging tools are definitive tests for differentiating a phyllodes tumor from a benign fibroadenoma . [ 13 ]
MIP is used for the detection of lung nodules in lung cancer screening programs which use computed tomography scans. MIP enhances the 3D nature of these nodules, making them stand out from pulmonary bronchi and vasculature.
Fibroadenoma of the breast is a benign tumor composed of a biplastic proliferation of both stromal and epithelial components. [ 12 ] [ 13 ] This biplasia can be arranged in two growth patterns: pericanalicular (stromal proliferation around epithelial structures) and intracanalicular (stromal proliferation compressing the epithelial structures ...
A ventilation/perfusion lung scan, also called a V/Q lung scan, or ventilation/perfusion scintigraphy, is a type of medical imaging using scintigraphy and medical isotopes to evaluate the circulation of air and blood within a patient's lungs, [1] [2] in order to determine the ventilation/perfusion ratio.
Unlike extensive-stage small cell lung cancer, limited-stage small cell lung cancer is potentially curable. [4] In limited small cell lung cancer, the median overall survival time is approximately 12–16 months, with five year survival rate of approximately 26% and long-term survival rate of approximately 4–5%. [19]
The use of more than 250,000 particles in a dose is controversial as little extra data is acquired from such scans while there is an increased risk of toxicity. [ 10 ] [ 11 ] Patients with pulmonary hypertension should be administered a minimum number of particles to achieve a lung scan (i.e. 60,000).
A lung biopsy is an interventional procedure performed to diagnose lung pathology by obtaining a small piece of lung which is examined under a microscope. [ 1 ] [ 2 ] Beyond microscopic examination for cellular morphology and architecture, special stains and cultures can be performed on the tissue obtained.
This allows for the detection of a pneumothorax with the absence of normal ‘lung-sliding’ and ‘comet-tail’ artifact (seen on the ultrasound screen). Compared with supine chest radiography , with CT or clinical course as the gold standard, bedside sonography has superior sensitivity (49–99% versus 27–75%), similar specificity (95 ...
