The torsion angle of the patellar tendon. A new CT parameter used for classification and treatment planning in femoropatellar syndrome.
No full textThe authors report a study conducted on 107 CT scans taken between January and December 2001 in 76 patients affected with femoropatellar pain, that did not benefit from physiotherapy. It is the purpose of this study to present a new CT scan parameter denominated torsion angle of the patellar tendon (TAPT) and to define an algorithm of treatment for this complex pathology based on the changes revealed by CT scan according to the Lyonese protocol. CT scan based on the Lyonese protocol provides an explanation of the symptoms and the objectivity via traditional parameters in 59.63% of patients. Thanks to the introduction of this new parameter (TAPT), which allows us to reveal the presence of an extrarotation of the proximal metaphysis of the tibia, the percentage of sensitivity with CT scan has been increased to 83.92%
Solid appearance of pancreatic serous cystadenoma diagnosed as cystic at ultrasound acoustic radiation force impulse imaging
No full textCONTEXT: Acoustic radiation force impulse imaging is an emerging imaging modality. The study of the pancreas is a new and promising application of ultrasound acoustic radiation force impulse imaging. CASE REPORT: We present the first case of pancreatic serous cystadenoma which mimics a solid neoplasm at conventional imaging (US and CT), correctly diagnosed as cystic at ultrasound acoustic radiation force impulse imaging. CONCLUSION: The "XXXX" values always measured at Virtual Touch tissue quantification allow the diagnosis of a pancreatic cystic lesion with simple fluid content suggesting the diagnosis of serous cystadenoma
Patologia pancreatica (cap. 17)
No full textQuesto libro presenta una analisi dettagliata delle applicazioni dei mezzi di contrasto ecografici a livello addominale. E’ presente una parte introduttiva che presenta la classificazione generale ed i principi fisici dei mezzi di contrasto ecografici, seguita da una parte speciale che descrive le applicazioni a livello del fegato, della milza, e del rene. Infine è presente una parte conclusiva ove vengono presentate alcune applicazioni speciali dei mezzi di contrasto ecografici a livello dei traumi dell’addome, del pancreas, della parete intestinale, e dei vasi addominali
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
