Biopsy, Needle
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.
Biopsy, Large-Core Needle
Biopsy, Fine-Needle
Endoscopic Ultrasound-Guided Fine Needle Aspiration
Conducting a fine needle biopsy with the aid of ENDOSCOPIC ULTRASONOGRAPHY.
Needlestick Injuries
Punctures
Incision of tissues for injection of medication or for other diagnostic or therapeutic procedures. Punctures of the skin, for example may be used for diagnostic drainage; of blood vessels for diagnostic imaging procedures.
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.
Pinus ponderosa
A plant species of the genus PINUS that contains isocupressic acid.
Neoplasm Seeding
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.
Post-Dural Puncture Headache
A secondary headache disorder attributed to low CEREBROSPINAL FLUID pressure caused by SPINAL PUNCTURE, usually after dural or lumbar puncture.
Endosonography
Ultrasonography of internal organs using an ultrasound transducer sometimes mounted on a fiberoptic endoscope. In endosonography the transducer converts electronic signals into acoustic pulses or continuous waves and acts also as a receiver to detect reflected pulses from within the organ. An audiovisual-electronic interface converts the detected or processed echo signals, which pass through the electronics of the instrument, into a form that the technologist can evaluate. The procedure should not be confused with ENDOSCOPY which employs a special instrument called an endoscope. The "endo-" of endosonography refers to the examination of tissue within hollow organs, with reference to the usual ultrasonography procedure which is performed externally or transcutaneously.
Spinal Puncture
Mediastinum
Pinus
Pinus sylvestris
A plant species of the genus PINUS which is the source of pinosylvin. It is sometimes called Scotch pine or Scots pine, which is also a common name for other species of this genus.
Image-Guided Biopsy
Conducting a biopsy procedure with the aid of a MEDICAL IMAGING modality.

Injections, Jet

Tomography, X-Ray Computed
Breast Diseases
Pathological processes of the BREAST.
Sensitivity and Specificity
Thyroid Nodule
A small circumscribed mass in the THYROID GLAND that can be of neoplastic growth or non-neoplastic abnormality. It lacks a well-defined capsule or glandular architecture. Thyroid nodules are often benign but can be malignant. The growth of nodules can lead to a multinodular goiter (GOITER, NODULAR).
Vacuum
Acupuncture Analgesia
Analgesia produced by the insertion of ACUPUNCTURE needles at certain ACUPUNCTURE POINTS on the body. This activates small myelinated nerve fibers in the muscle which transmit impulses to the spinal cord and then activate three centers - the spinal cord, midbrain and pituitary/hypothalamus - to produce analgesia.
Mediastinal Diseases
Disorders of the mediastinum, general or unspecified.
Blood-Borne Pathogens
Infectious organisms in the BLOOD, of which the predominant medical interest is their contamination of blood-soiled linens, towels, gowns, BANDAGES, other items from individuals in risk categories, NEEDLES and other sharp objects, MEDICAL WASTE and DENTAL WASTE, all of which health workers are exposed to. This concept is differentiated from the clinical conditions of BACTEREMIA; VIREMIA; and FUNGEMIA where the organism is present in the blood of a patient as the result of a natural infectious process.
Magnetic Resonance Imaging, Interventional
Breast
Anesthesia, Conduction
Infusions, Intraosseous
Shigella flexneri
Robotics
Acupuncture
The occupational discipline of the traditional Chinese methods of ACUPUNCTURE THERAPY for treating disease by inserting needles along specific pathways or meridians.
Ultrasonography, Mammary
Mediastinal Neoplasms
Tumors or cancer of the MEDIASTINUM.
