The rate of detection of breast cancer by MRI, while other methods of radiological diagnosis are not sufficiently informative, ranges from 5.2 to 26.3 per cent. Suspicious breast tumors of category BI-RADS 4, 5 show morphological image-guided biopsy verification, in particular MRI with contrast. Purpose. To show the possibilities and features of carrying out MRI-guided vacuum breast biopsy, including after aesthetic breast augmentation. Material and methods. A comprehensive X-ray, ultrasound and MRI examination of 54 women aged between 28 and 70 years with different breast tumors was conducted. Of these, five were detected only by breast MRI with contrast, and were morphologically verified by MRI-guided vacuum aspiration biopsy. Results. 14 of the 54 patients with breast mass were diagnosed with breast cancer and 26 were diagnosed with benign diseases. The effectiveness of comprehensive examination and low-invasive high-tech MRI-guided procedures in early refined screening for breast cancer, including after aesthetic breast augmentation, has been demonstrated. MRI-guided vacuum-assisted breast biopsy is a fast, safe and accurate diagnostic method of morphological verification of suspicious breast tumors that do not have X-ray and ultrasound.

Energy Subtraction

Dual-energy subtraction digital tomosynthesis with pulsed X-ray and rapid kV switching was used to examine calcifications in pulmonary lesions. The digital tomosynthesis system used included a conventional fluororadiographic TV unit with linear tomographic capabilities, a high resolution videocamera, and an image processing unit. Low-voltage, high-voltage, and soft tissue subtracted or bone subtracted tomograms of any desired layer height were reconstructed from the image data acquired during a single tomographic swing. Calcifications, as well as their characteristics and distribution in pulmonary lesions, were clearly shown. The images also permitted discrimination of calcifications from dense fibrotic lesions. This technique was effective in demonstrating calcifications together with a solitary mass or disseminated nodules.

The preparation and full NMR (H1,C13 and P31) characterisation of three R3PAu (2mba) complexes, Where R = Et, Ph and Cy, and 2mba is the anion derived from 2-mercaptobenzoic acid is reported. An interesting solvent dependence in the 1H spectra is rationalised in terms of competing intra- and inter-molecular hydrogen bonding. An X-ray analysis of the [Ph3PAu(2mba)] species reveals a linear P—Au—S arrangement and association in the lattice via the familar carboxylic acid dimer motif. The in Vitro cytotoxicity against seven human tumout lines is also described. The complexes display moderate to very high activity. Particularly noteworthy is their greater activity against the H226 cell line (non-small cell lung cancer) compared with that displayed by a range of cytotoxic drugs.

Background: Chest x-ray (CXR) is the first-line test for lung cancer in many settings. Previous research has suggested that higher utilisation of CXR is associated with improved outcomes. Aim: To explore the associations between characteristics of general practices and frequency of investigation with CXR. Design & Setting: Retrospective observational study of English general practices. Method: We constructed a database of English general practices containing number of CXRs requested and data on practices for 2018, including patient & staff demographics, smoking prevalence, deprivation and patient satisfaction indicators. Mixed effects Poisson modelling was used to account for variation due to chance and to estimate the amount of remaining variation that could be attributed to practice and population characteristics. Results: There was substantial variation in GP CXR rates (median 34 per 1000 patients, IQR 26-43). Only 18% of between-practice variance in CXR rate was accounted for by recorded characteristics. Higher practice scores for continuity and communication skills and higher proportions of smokers, Asian and mixed ethnic groups, and patients aged >65 were associated with increased CXR rates. Higher patient satisfaction scores for access and with greater proportions of male and patients of black ethnicity were associated with lower CXR rates. Conclusion: Substantial variation was found in CXR rates beyond that expected by chance, which could not be accounted for by practices’ recorded characteristics. Since other research has indicated that increasing CXR rates can lead to earlier detection, supporting practices which currently investigate infrequently could be an effective strategy to improve lung cancer outcomes.
