The purpose of this study was to evaluate the thin-section helical CT findings of intraductal papillary mucinous tumors and to investigate whether helical CT could distinguish between malignant and benign intraductal papillary mucinous tumors. Twenty-seven patients (nine with malignant and 18 with benign intraductal papillary-mucinous tumors) underwent thin-section (3- or 5-mm) helical CT. Two-phase enhanced CT was started 30 and 60-70 sec after injection of contrast material at 3 ml/sec. In six patients (22.2%), a bulging papilla was depicted on CT. Twenty-five patients (92.6%) had a dilated main pancreatic duct. Cystic lesions were seen in 25 patients (92.6%). Thirteen lesions (48%) were located in the uncinate process, seven (25.9%) were in the head, two (7.4%) were in the body, and three (11%) were in the tail. The cystic lesion was unilocular in five patients (18.5%) and multilocular with a lobulated margin in 20 patients (74%). Communication between the main pancreatic duct and the cystic lesion was depicted in 19 patients (70.4%). The papillary projections corresponding to 3-mm or larger papillary neoplasms were depicted in five patients (18.5%). The bulging papilla was more often observed in malignant than in benign int...Continue Reading

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule.
