Needles: Sharp instruments used for puncturing or suturing.Biopsy, Needle: Removal and examination of tissue obtained through a transdermal needle inserted into the specific region, organ, or tissue being analyzed.Biopsy: Removal and pathologic examination of specimens in the form of small pieces of tissue from the living body.Radiography, Interventional: Diagnostic and therapeutic procedures that are invasive or surgical in nature, and require the expertise of a specially trained radiologist. In general, they are more invasive than diagnostic imaging but less invasive than major surgery. They often involve catheterization, fluoroscopy, or computed tomography. Some examples include percutaneous transhepatic cholangiography, percutaneous transthoracic biopsy, balloon angioplasty, and arterial embolization.Jugular Veins: Veins in the neck which drain the brain, face, and neck into the brachiocephalic or subclavian veins.Ultrasonography, Interventional: The use of ultrasound to guide minimally invasive surgical procedures such as needle ASPIRATION BIOPSY; DRAINAGE; etc. Its widest application is intravascular ultrasound imaging but it is useful also in urology and intra-abdominal conditions.Biopsy, Large-Core Needle: The use of needles usually larger than 14-gauge to remove tissue samples large enough to retain cellular architecture for pathology examination.Biopsy, Fine-Needle: Using fine needles (finer than 22-gauge) to remove tissue or fluid specimens from the living body for examination in the pathology laboratory and for disease diagnosis.RNA, Guide: Small kinetoplastid mitochondrial RNA that plays a major role in RNA EDITING. These molecules form perfect hybrids with edited mRNA sequences and possess nucleotide sequences at their 5'-ends that are complementary to the sequences of the mRNA's immediately downstream of the pre-edited regions.Image-Guided Biopsy: Conducting a biopsy procedure with the aid of a MEDICAL IMAGING modality.Needle Sharing: Usage of a single needle among two or more people for injecting drugs. Needle sharing is a high-risk behavior for contracting infectious disease.Endoscopic Ultrasound-Guided Fine Needle Aspiration: Conducting a fine needle biopsy with the aid of ENDOSCOPIC ULTRASONOGRAPHY.Syringes: Instruments used for injecting or withdrawing fluids. (Stedman, 25th ed)Sensitivity and Specificity: Binary classification measures to assess test results. Sensitivity or recall rate is the proportion of true positives. Specificity is the probability of correctly determining the absence of a condition. (From Last, Dictionary of Epidemiology, 2d ed)Neoplasm Seeding: The local implantation of tumor cells by contamination of instruments and surgical equipment during and after surgical resection, resulting in local growth of the cells and tumor formation.Equipment Design: Methods of creating machines and devices.Needlestick Injuries: Penetrating stab wounds caused by needles. They are of special concern to health care workers since such injuries put them at risk for developing infectious disease.Sentinel Lymph Node Biopsy: A diagnostic procedure used to determine whether LYMPHATIC METASTASIS has occurred. The sentinel lymph node is the first lymph node to receive drainage from a neoplasm.Bronchoscopy: Endoscopic examination, therapy or surgery of the bronchi.
  • The tumor was resected en-bloc, and reported as a metastatic squamous cell carcinoma. (ismics.org)
  • PET/CT-guided biopsy had a sensitivity of 98%, specificity of 100%, positive predictive value of 100%, negative predictive value of 95%, and accuracy of 98% for detecting malignancy. (auntminnie.com)
  • Multiple samples obtained with a 20-guage coaxial needle are adequate and have a high success rate for various molecular studies for lung malignancy. (amegroups.com)
  • Proper cut-off values affecting the conversion to cone-beam CT guided PTNB were 1.65 cm (sensitivity 68.4%, specificity 71.1%) in short-axis diameter and 29.50 HU (sensitivity 65.8%, specificity 65.8%) in CT attenuation value. (koreamed.org)
  • The number of needle passes, type of guidance, change in hematocrit level, and adequacy of specimens for histologic analysis were evaluated. (argonmedical.com)
  • Bleeding in the biopsy tract has been studied for its ability to decrease the risk of pneumothorax with indefinite results in the previous studies. (jbsr.be)
  • We discuss two interesting cases at our institution where CTGB of the cervical spine during workup negated the need for open surgical biopsy or further surgical intervention. (theassr.org)
