one of most challenging problems in neuroradiology is differentiation lesions in brain and another challenging problems is post op. or post radiation/post chemotherapy changes vs recurrence /remnant. on this lecture i am going to show you many cases that on the basis of new technique such as swi, pwi, mrs, cine mri, dti and tractography we can achieve the final diagnosis.
Core carrier techniques are unique among the various root canal filling techniques for delivering and compacting gutta-percha in the prepared root canal system. Thermafil (TF), considered the major core carrier device, is provided as an obturator consisting of a master core coated with thermoplasticized gutta-percha. We have devised a thermoplasticized gutta-percha filling technique using a pol...
