[++Scintimammography: a new imaging technique for diagnosis and follow-up of breast cancer].

99m Tc MiBi has emerged as a new imaging technique for primary breast carcinomas. The aim of this study was to analyze the diagnostic performance and the additional information provided by scintimammography (SMN). Two hundred and forty consecutive women referred to surgery for abnormalities breast or suspicious breast cancer were scanned before surgery.

[Autonomous thyroid adenoma. Value of thallium scintigraphy and pathology].

Clinical, biological, scintigraphic (99mTc, 123I, 201Tl) and histological data were reviewed in 90 patients operated for autonomous adenomas (hot nodules). Analysis of the data gave the following results: 74.4% of the nodules were solitary and 25.

[Contribution of TRH test and anti-TPO antibody assay in the screening of infraclinical hypothyroidism].

The upper limit of normal TSH levels, determined with a second generation kit (RIA-Gnost TSH, Behring) was set at 2.8 microU/ml. These TSH levels define pituitary reactivity in euthyroid subjects.

Correlation of 99Tcm-sestamibi SPECT with coronary angiography in general hospital practice.

One hundred and twenty-eight patients had a stress test with sestamibi injection and a coronarography within 2 months of the sestamibi study. Sestamibi studies were reconstructed using Hanning 0.65 and Wiener 1.

[Can benign and malignant thyroid nodules be differentiated with thallium 201?].

The merits of Thallium 201 radionuclide scanning of the thyroid mentioned as soon as 1976 by PALERMO have been confirmed in the 16 last studies published in the international literature. Over 1601 examinations, authors showed that any cold nodule (Tc 99 m or I 123) which preferentially fixes Thallium 201 as compared to surround thyroid tissue must be operated since some of them are thyroid cancer carriers, some others are carriers of a traditional follicular adenoma or Hurthle-cell adenoma, or a follicular adenoma associated with varied cell atypisms which make difficult the diagnosis between benign and malignant nodules. The analysis of the results published show a 91.

[Determination of thyroid peroxidase antibodies in common thyroid pathology. Methodological and clinical approach].

Thyroid peroxidase antibody levels were measured in 409 patients who came to the thyroid pathology consultation of our Institution between September, 1990, and November, 1991, and were compared with a reference population. In the first 231 patients, we compared the results obtained with two commercial kits. The correlation coefficient between both populations of results was assessed to be 0.

Kidney depth measured by using 99Tcm-DMSA. Comparison with CAT scan: review of 50 measurements.

Measurement of kidney depths using computed axial tomographic (CAT) scans, considered as the gold standard, has been compared in 25 patients with depth measured using an isotopic method (99Tcm-DMSA). 99Tcm-DMSA underestimates renal depth in 78% of the cases (mean underestimation: 0.78 cm).
