PURPOSE This study presents the steps and criteria involved in the series of image registrations used clinically during the planning and dose delivery of focal high dose-rate (HDR) brachytherapy of the prostate. MATERIAL AND METHODS Three imaging modalities - Magnetic Resonance Imaging (MRI), Magnetic Resonance Spectroscopic Imaging (MRSI), and Computed Tomography (CT) - were used at differen...

Carcinomas of the rectum are associated with a significant local and distant recurrence rate. Not all patients are appropriate candidates for preoperative radiation therapy. Preoperative identification of those most likely to benefit from neoadjuvant therapy is important. There is no general consensus on the role of endorectal ultrasonography, computed tomography (CT), and magnetic resonance im...

I feel somewhat relaxed and freer since I resigned from the position of Vice Minister of Finance for International Affairs about a month ago. At least now I don’t have to worry about what I say about the yen/US dollar rate for the wire people who used to follow me all over the world. I would like to remind you that what I say today does not necessarily reflect the official views of the Japanese...

Introduction Geriatric patients and their relative fragility with respect to younger patients represent a surgical dilemma for the general surgeon. This has led surgeons to adopt "tailored" techniques and strategies to treat them. The rapid increase of this aged population has given the clinician the chance to push forward the knowledge on this subset of patients and challenge previous concepts...

Magnetic resonance imaging may improve the staging of prostate cancer compared with clinical evaluation alone, computerized tomography, or transrectal ultrasound, and it allows simultaneous and detailed evaluation of prostatic, periprostatic, and pelvic anatomy. Endorectal magnetic resonance imaging and magnetic resonance spectroscopic imaging (endoMRI/MRSI) allow better visualization of the zo...

A previously proposed two-terminal carbon-nanotube-based device with closed-loop feedback is demonstrated through in situ scanning electron microscopy (SEM) experiments. The pull-in/pull-out tests were carried out using a multi-walled carbon nanotube (MWCNT) welded to a conductive probe attached to a nanomanipulator. The MWCNTs were cantilevered over a gold electrode and electrostatically actua...

Endorectal ultrasonography (ERUS) and magnetic resonance imaging (MRI) allow exploring the morphology of the rectum in detail. Use of such data, especially assessment of the rectal wall, is an important tool for ascertaining the perianal fistula localization as well as stage of the cancer and planning it appropriate treatment, as stage T3 tumors are usually treated with neoadjuvant therapy, whe...

Historically, in female pseudohermaphrodites a staged procedure with early clitoral reduction and delayed vaginoplasty was often the treatment of choice. In recent years several authors have described 1-stage genitoplasty that is performed in the first year of life. The 1stage procedure for clitoroplasty and vaginal exteriorization is preferable for an optimal functional and cosmetic result. Be...
