The imagistic diagnosis of the pathology of the breast implant

Catedra Radiologie şi imagistică USMF „Nicolae Testemiţanu”, IMSP Institutul OncologicThe abstract study evaluates the algorithm of diagnosis of breast implant complication by means of medical imaging methods. The idea of implantation exists for more centuries having been practis since in 1962. Knowledge concerning technical and medical modern possibilities, advantages, and risks, complications of breast implant and appearance of cancer in the future are initial conditions of objective judgment in monitoring patients with breast prosthesis. In this section, we have analyzed two aspects, which show the correlation between breasts implant: - assessing the integrity of implant (early detection and late complications), - the diagnosis of breast cancer or some other diseases of mammary gland in holders of mammary implants; finally estimating, sensitivity, specificity and effectiveness of each separate imaging method and complexity. In studiul dat se integreaza evaluarea algoritmului de dignostic a complicatiilor implantului mamar prin intermediul metodelor imagisticii medicale. Ideea implantarii exista de mai multe secole, insa pentru prima data aceasta practica a fost utilizata in 1962. Cunoştinţele referitoare la posibilităţile tehnologice şi medicale moderne, avantajele, riscurile, complicaţiile implantului mamar şi apariţia unui eventual cancer sunt primordiale pentru a lua o decizie obiectivă in monitorizarea pacientelor cu proteze mamare. Am analizat două aspecte, care evidenţiază corelaţia dintre imageria sînilor şi implantele mamare: - evaluarea integrităţii implantelor (detecţia complicaţiilor precoce şi tardive), - diagnosticul cancerului de sîn sau a altor patologii a glandelor mamare la purtătoarele de implante mamare; estimand, in final, sensibilitatea, specificitatea şi eficacitatea fiecarei metode imagistice separat şi în complexitate

The role of digital tomosynthesis in laryngeal cancer: comparison with radiography and computed tomography

Introduction. Digital tomosynthesis is a relatively new imaging modality that is already used in the diagnosis of breast cancer and has shown promising results in evaluating patients with pulmonary, osteoarticular, and other pathologies. However, up to date, there are no published studies related to the usefulness of digital tomosynthesis in the evaluation of patients with laryngeal cancer. The purpose of this study was to evaluate the clinical role of digital tomosynthesis in the diagnosis of laryngeal cancer and compare the imaging results with those obtained by digital radiography and computed tomography. Material and methods. The study was carried out between 2015 and 2019 at the Institute of Oncology in the Republic of Moldova and included 253 consecutive patients with laryngeal cancer referred to the Institute of Oncology during this period. All patients underwent digital radiography and digital tomosynthesis investigations. In 41 patients who provided written informed consent, computed tomography was performed. The results of all imaging investigations were compared. Results. The statistical analysis revealed a high degree of agreement and a strong linear correlation between the data obtained with digital tomosynthesis and computed tomography, as well as concordance correlation coefficients for different parameters between 0.63 and 1.0 (mean value = 0.82±0.11). For comparison, the concordance correlation coefficients for the same parameters obtained for digital radiography versus computed tomography ranged between 0.08 and 0.93 (mean value = 0.43±0.25). An updated imaging algorithm that includes digital tomosynthesis has also been proposed for investigating patients with suspected laryngeal cancer. Conclusions. The study demonstrated the usefulness of digital tomosynthesis for the evaluation of patients with laryngeal cancer. When compared to computed tomography, which is considered the gold standard, digital tomosynthesis revealed a much higher performance compared to digital radiography. Considering the availability of low-dose protocols for digital tomosynthesis, the modality might also be helpful for laryngeal cancer screening in a high-risk population. However, new studies are also required to confirm our findings and define the place of digital tomosynthesis in the imaging algorithm for patients with laryngeal cancer
