| nuclear magnetic resonance imaging | A special imaging technique used to image internal stuctures of the body, particularly the soft tissues. An MRI image is often superior to a normal X-ray image. It uses the influence of a large magnet to polarize hydrogen atoms in the tissues and then monitors the summation of the spinning energies within living cells. Images are very clear and are particularly good for soft tissue, brain and spinal cord, joints and abdomen. These scans may be used for detecting some cancers or for following their progress. Acronym: MRI (11 Nov 1997) |

| dark field imaging | <microscopy> Using a single diffracted beam to form the image in a transmission electron microscope. This causes all regions of the specimen not of the same crystal structure and orientation as the region which produced the diffracted beam to be represented as very dark in the final image, allowing phase differentiation visually in the transmission electron microscope. (05 Aug 1998) |
| diagnostic imaging | Any visual display of structural or functional patterns of organs or tissues for diagnostic evaluation. It includes measuring physiologic and metabolic responses to physical and chemical stimuli, as well as ultramicroscopy. (12 Dec 1998) |
| dipyridamole-thallium imaging | <radiology> Myocardial perfusion imaging for patients who cannot exercise, dipyridamole, potent coronary vasodilator, dose: 300 mg IV, side effects relieved by aminophyllin, thallium given when: symptomatic, HR increased 10 bpm, diastolic BP decreased 10 mm Hg, 45 min after PO dose (12 Dec 1998) |
| imaging | Radiological production of a clinical image using X-rays, ultrasound, computed tomography, magnetic resonance, radionuclide scanning, thermography, etc.; especially, cross-sectional imaging, such as ultrasonography, CT, or MRI. Origin: see image (05 Mar 2000) |
| imaging agents | Proteins developed to act as imaging or contrast agents for use with various types of bodyscanners. The proteins, usually antibodies, bind to specific tissue types, usually tumours, and allow the scanner to distinguish those tissues from the surrounding tissue very easily. (14 Nov 1997) |
| imaging department | The diagnostic radiology department. See: imaging, radiology. (05 Mar 2000) |
| inflammation: gallium imaging | <radiology> Pathophysiology: leakage of protein-bound Ga-67 into extracellular space secondary to increased capillary permeability, Ga-67 is preferentially bound to nonviable PMNs and macrophages, leukocyte incorporation (rich in lactoferrin), bacterial uptake (siderophores), inflammtory tissue stimulates lactoferrin production for chronic abdominal inflammation: 67% sensitivity; 64% specificity; 13% false negatives; 5% false positive, dose: 5 mCi; imaging: 24, 48, 72 hours, diffuse uptake in peritonitis, localised uptake in acute pyogenic abscess, phlegmon, acute cholecystitis, acute pancreatitis, acute gastritis, diverticulitis, inflammatory bowel disease, surgical wound, pyelonephritis, perinephric abscess see: gallium indications, gallium vs. Indium (12 Dec 1998) |
| echo-planar imaging | A type of magnetic resonance imaging that uses only one nuclear spin excitation per image and therefore can obtain images in a fraction of a second rather than the minutes required in traditional mri techniques. It is used in a variety of medical and scientific applications. (12 Dec 1998) |
| thyroid imaging | <radiology> Tc-99m pertechnetate 6 mCi, I-123 sodium iodide 200 - 400 uCi PO (12 Dec 1998) |
| ultrasound imaging | <investigation, procedure> A technique in which high-frequency sound waves are bounced off internal organs and the echo pattern is converted into a 2 dimensional picture of the structures beneath the transducer. (12 May 1997) |
| kidney: gallium imaging | <radiology> 10-20% of Ga-67 excreted via GU tract; no renal activity after 24hrs abnormal uptake (images at 48-72 hrs): tumour, primary renal tumour (variable uptake), lymphoma/leukaemia, metastases (e.g., melanoma), inflammation, acute pyelonephritis (88% sensitivity); abscess, lobar nephroma, others, collagen vascular disease, vasculitis, Wegener granulomatosis, amyloidosis, haemochromatosis, hepatic failure, antineoplastic drugs, transplant rejection: acute, chronic, ATN see also: gallium: indications (12 Dec 1998) |
| liver metastases: ultrasound imaging | <radiology> Echogenic (25%), colonic carcinoma, hepatocellular carcinoma, treated breast carcinoma mixed echogenicity (37.5%), breast carcinoma, rectal carcinoma, lung carcinoma, stomach carcinoma, anaplastic cancer, cervical carcinoma, carcinoid hypoechoic (37.5%), lymphoma, pancreatic carcinoma, cervical carcinoma, lung carcinoma (adenocarcinoma), nasopharyngeal carcinoma see: liver metastases (12 Dec 1998) |
| lung: gallium imaging | <radiology> Scans at 48 hrs because 50% of normals show activity at 24 hrs, focal uptake, primary pulmonary malignancy, benign disorder: granuloma, abscess, pneumonia, silicosis, multifocal/diffuse uptake, infection, TB: active lesion, miliary TB, rapidly progressive TB pneumonia, PCP: unimpressive symptoms and CXR, CMV, inflammation: sarcoid, interstitial lung disease (pneumoconiosis, idiopathic pulmonary fibrosis, lymphangitic carcinomatosis), radiation pneumonitis, drugs: bleomycin, amiodarone, contrast lymphangiography (in 50%) see: gallium: indications, uptake with normal chest film (12 Dec 1998) |
| adoptive transfer | Form of passive immunization where previously sensitised immunologic agents (cells or serum) are transferred to non-immune recipients. When transfer of cells is used as a therapy for the treatment of neoplasms, it is called adoptive immunotherapy (immunotherapy, adoptive). (12 Dec 1998) |
