  • benign
  • An FNA is the most common type of biopsy used for salivary gland cancer, and has been shown to produce accurate results when differentiating between benign and malignant tumours. (wikipedia.org)
  • Pathologic examination of a biopsy can determine whether a lesion is benign or malignant, and can help differentiate between different types of cancer. (wikipedia.org)
  • Efficacy is considered optimal if the diagnosis by transcutaneous biopsy is identical to the surgical specimen in case of malignancy or in line with clinical follow-up when benign. (wikipedia.org)
  • Features of benign lesion are: hyperechoic, having coarse, dysmorphic or curvilinear calcifications, comet tail artifact (reflection of a highly calcified object), absence of blood flow in the nodule, and presence of cystic (fluid-filled) nodule. (wikipedia.org)
  • bone
  • Should she find no degeneration, etc., we'll schedule a bone biopsy - OUCH! (medhelp.org)
  • A unicameral bone cyst, also known as a simple bone cyst, is a cavity filled with a yellow-colored fluid. (wikipedia.org)
  • He believed that the chemical composition of the fluid found in the bone cyst was similar to the chemical make-up in serum. (wikipedia.org)
  • Cohen theorized that the unicameral bone cyst occurs when interstitial fluids in cancellous bones quickly accumulate in one region from blockage. (wikipedia.org)
  • The treatment can involve or incorporate one or more of the following surgical methods, which are performed by a pediatric orthopedic surgeon: Curettage: Surgeons create an incision or opening in the bone to drain out the fluids inside the cyst. (wikipedia.org)
  • The second is performing an aspirate (bone marrow, cerebrospinal fluid, etc. (wikipedia.org)
  • incision
  • The needle normally has a lateral ("from the side") opening and can be rotated allowing multiple samples to be collected through a single skin incision. (wikipedia.org)
  • examination
  • Cytologic examination of pleural fluid is only diagnostic in 60-80% of patients with metastatic pleural involvement and in less than 20% in patients with mesothelioma. (medscape.com)
  • Examination by a cytopathologist of the fluid aspirated from the cyst may also help with this diagnosis. (wikipedia.org)
  • A biopsy is a medical test commonly performed by a surgeon, interventional radiologist, or an interventional cardiologist involving extraction of sample cells or tissues for examination to determine the presence or extent of a disease. (wikipedia.org)
  • tumor
  • There are two types of liquid biopsy (which is not really a biopsy as they are blood tests that do not require a biopsy of tissue): circulating tumor cell assays or cell-free circulating tumor DNA tests. (wikipedia.org)
  • By detecting and quantifying genomic alterations in CTCs and cell-free DNA in blood, liquid biopsy can provide real-time information on the stage of tumor progression, treatment effectiveness, and cancer metastasis risk. (wikipedia.org)
  • The tests analyze circulating tumor cells (CTCs) Analysis of individual CTCs demonstrated a high level of heterogeneity seen at the single cell level for both protein expression and protein localization and the CTCs reflected both the primary biopsy and the changes seen in the metastatic sites. (wikipedia.org)
  • surgical
  • When the specimen is evaluated, in addition to diagnosis, the amount of uninvolved tissue around the lesion, the surgical margin of the specimen is examined to see if the disease has spread beyond the area biopsied. (wikipedia.org)
  • withdrawn
  • The improvement includes that the instrument is constructed to take multiple biopsy samples without being withdrawn from the body. (google.ca)
  • After the needle is in the proper position, tissue or fluid will be withdrawn. (stdavids.com)
  • After the needle is in the proper place, tissue or fluid will be withdrawn. (epnet.com)
  • The instrument is constructed to take multiple biopsy samples without being withdrawn from the body by including a storage space along the axis of the device suitable for storage of multiple, successively taken samples. (google.com)
  • tissues
  • MRI Biopsy: The removal of cells or tissues so they can be viewed under a microscope by a pathologist to check for signs of cancer. (wikipedia.org)
  • To perform an aspirate in liquid tissues, a needle is inserted inside the body and a sample is extracted. (wikipedia.org)
  • body
  • Your doctor may use images of the inside of your body to help guide the needle. (stdavids.com)
  • Depending on its cause, pleuritic chest pain may be accompanied by other symptoms: Dry cough Fever and chills Rapid, shallow breathing Shortness of breath Fast heart rate Sore throat followed by pain and swelling in the joints The pleural space can be invaded by fluid, air, and particles from other parts of the body, which fairly complicates diagnosis. (wikipedia.org)
  • cavity
  • In particular, pleural effusion (fluid build-up in the chest cavity) may be found in several other diseases including lung cancer, heart failure and pneumonia. (mdanderson.org)
  • Sometimes a thyroid nodule presents as a fluid-filled cavity called a thyroid cyst. (wikipedia.org)
  • tumour
  • Flow cytometry detects antibodies linked to tumour cell surface antigens in fluid samples or cell suspensions. (wikipedia.org)
  • blood
  • In practice of this invention, the detoxified blood from an artificial kidney is supplied to the vein through a hypodermic needle which penetrates the inlet septum, the inlet plenum, the inlet channel and the inlet valve and toxified blood is supplied from the vein to the artificial kidney through the outlet valve, the outlet channel, the outlet plenum and an outlet needle which penetrates the outlet septum. (google.ca)
  • 2. The hemodialysis port assembly of claim 1 wherein the separate channel means includes means for substantially suppressing circulation of detoxified blood in a short circuit including said inlet needle, said first channel, said second channel, and said outlet needle. (google.ca)
  • 3. The hemodialysis port assembly of claim 1 characterized by that the cross-sectional area of the first channel through which the detoxified blood or fluid is conducted is substantially equal to the cross-sectional area of the second channel through which the toxified blood or fluid is conducted. (google.ca)
  • This technological development could make it possible to diagnose and manage cancer from repeated blood tests rather than from a traditional biopsy. (wikipedia.org)
  • It can be divided into six categories: Blood tests may be done prior to or in lieu of a biopsy. (wikipedia.org)
  • characteristics
  • Attempts have been made to predict survival based on the clinical characteristics of pleural fluid. (bmj.com)
  • The most appropriate method of biopsy for a patient depends upon a variety of factors, including the size, location, appearance and characteristics of the abnormality. (wikipedia.org)
