| 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) |
| through transfer imaging | The production of an ultrasound image by detection and analysis of sound on the opposite side of the body from the emitting transducer. Synonym: through transfer imaging. (05 Mar 2000) |
| thyroid imaging | <radiology> Tc-99m pertechnetate 6 mCi, I-123 sodium iodide 200 - 400 uCi PO (12 Dec 1998) |
| transfer imaging | The production of an ultrasound image by detection and analysis of sound on the opposite side of the body from the emitting transducer. Synonym: through transfer imaging. (05 Mar 2000) |
| 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) |
