Authors: Jiang ZZ, He C, Wang DQ, Shen HL, Sun JL, Gan WN, Lu JY, Liu XT Abstract In December 2019, an outbreak of coronavirus infection emerged in Wuhan, Hubei Province of China, which is now named Coronavirus Disease 2019 (COVID-19). The outbreak spread rapidly within mainland China and globally. This paper reviews the different imaging modalities used in the diagnosis and treatment process of COVID-19, such as chest radiography, computerized tomography (CT) scan, ultrasound examination, and positron emission tomography (PET/CT) scan. A chest radiograph is not recommended as a first-line imaging modality for COVI...

RESUMEN Paciente de 20 a ños que presentó aumento de volumen facial izquierdo. Estudiado con ecografía, TAC y biopsia quirúrgica. Se establece el diagnóstico de hipertrofia maseterina unilateral idiopática. La hipertrofia maseterina es un desorden benigno que puede manifestarse de forma unilateral o bilateral, que pro voca una asimetría facial, frecuentemente asintomática. Se han propuesto varios tratamientos, siendo la infiltración con toxina botulínica tipo A un tratamiento mínimamente invasivo y eficaz.ABSTRACT A 20-year-old patient who present...

(Society of Nuclear Medicine and Molecular Imaging) New research confirms the high impact of PSMA PET/CT in the detection and management of recurrent disease in prostate cancer patients. In initial results from a multicenter trial assessing the impact of 18F-DCFPyL prostate-specific membrane antigen positron emission tomography/computed tomography (PSMA PET/CT), a PET-directed change in management was observed in two-thirds of patients. The research was presented at the Society of Nuclear Medicine and Molecular Imaging's 2020 Virtual Annual Meeting.

;t Alpár Tamás Masszi András Masszi Csaba Bödör Recent advances in molecular technologies enable sensitive and quantitative assessment of circulating tumor DNA, offering a noninvasive disease monitoring tool for patients with malignant disorders. Here, we demonstrated on four follicular lymphoma cases that circulating tumor DNA based EZH2 mutation analysis performed by a highly sensitive droplet digital PCR method may be a valuable treatment monitoring approach in EZH2 mutant follicular lymphoma. EZH2 variant allele frequencies changed in parallel with the volume of metabolically ac...

There is growing evidence regarding the imaging findings of Coronavirus Disease 2019 (COVID-19), in chest X-ray and Computed Tomography scan (CT). At this moment, the role of Lung Ultrasonography (LUS) has yet to be explored. The main purpose of this study is to evaluate the correlation between LUS findings and chest CT in confirmed (positive RT-PCR) or clinically highly suspicious (dyspnea, fever, myasthenia, gastrointestinal symptoms, dry cough, ageusia or anosmia) of COVID-19 patients. This prospective study was carried out in the emergency department (ED), confirmed or clinically highly suspicious COVID-19 patients wer...

ConclusionsOur discussion details a comprehensive literature review of extramedullary pulmonary involvement in Waldenstrom ’s macroglobulinemia. Establishing a malignant etiology for pleural effusion in Waldenstrom’s macroglobulinemia can be challenging, as standard techniques may be insensitive. Allele-specific polymerase chain reaction for detecting MYD88 L265P mutations is more sensitive for confirming lymphoplas macytic lymphoma/Waldenstrom’s macroglobulinemia in pleural fluid. Extramedullary pulmonary involvement usually presents post-diagnosis of Waldenstrom’s macroglobulinemia and responds we...

Angelis Carlo A minimally invasive implant treatment approach for future full arch implant prosthetic rehabilitations of trophic jaws represents a challenge. An optimal implant planning is strongly related with an accurate merge of the prosthetic information and the radiographic data. To comply with that, most computer aided implantology (CAI) systems require additional steps, as radiographic stents or fiducial markers to overlap digital jaw scans to cone beam computed tomography (CBCT) data. Using dynamic CAI, residual teeth (up to three) make it possible for the merge to avoid new radiographic scans. An addition...
