conferenceObject PET/CT for primary staging of rectal cancer patients with and without extramural vascular invasion detected by MR (EMVI-MR)(2016) QUEIROZ, M.; ORTEGA, C.; MORITA, T.; VIANA, P.; ZAGATTI, M.; BLASBALG, R.; MENEZES, M.; BUCHPIGUEL, C.- Multidetector CT Evaluation of the Postoperative Pancreas(2012) YAMAUCHI, Fernando I.; ORTEGA, Cinthia D.; BLASBALG, Roberto; ROCHA, Manoel S.; JUKEMURA, Jose; CERRI, Giovanni G.Several pancreatic diseases may require surgical treatment, with most of these procedures classified as resection or drainage. Resection procedures, which are usually performed to remove pancreatic tumors, include pancreatoduodenectomy, central pancreatectomy, distal pancreatectomy, and total pancreatectomy. Drainage procedures are usually performed to treat chronic pancreatitis after the failure of medical therapy and include the Puestow and Frey procedures. The type of surgery depends not only on the patient's symptoms and the location of the disease, but also on the expertise of the surgeon. Radiologists should become familiar with these surgical procedures to better understand postoperative changes in anatomic findings. Multidetector computed tomography is the modality of choice for identifying normal findings after surgery, postoperative complications, and tumor recurrence in patients who have undergone pancreatic surgery.

- Findings of Pelvic Endometriosis at Transvaginal US, MR Imaging, and Laparoscopy(2011) CHAMIE, Luciana Pardini; BLASBALG, Roberto; PEREIRA, Ricardo Mendes Alves; WARMBRAND, Gisele; SERAFINI, Paulo CesarEndometriosis is a common multifocal gynecologic disease that manifests during the reproductive years, often causing chronic pelvic pain and infertility. It may occur as invasive peritoneal fibrotic nodules and adhesions or as ovarian cysts with hemorrhagic content. Although findings at physical examination may be suggestive, imaging is necessary for definitive diagnosis, patient counseling, and treatment planning. The imaging techniques that are most useful for preoperative disease mapping are transvaginal ultrasonography (US) after bowel preparation, and magnetic resonance (MR) imaging. Initial transvaginal US is a reliable technique for detecting rectosigmoid endometriotic lesions. MR imaging is indicated as a complementary examination in complex cases of endometriosis with extensive adhesions and ureteral involvement. Peritoneal endometriotic implants are typically hypoechoic on transvaginal US images and demonstrate low signal intensity on T2-weighted MR images. Endometriotic implants most commonly are found in retrocervical and rectosigmoid sites, followed by the vagina, bladder, and ureters. Cysts with low-level internal echoes and echogenic peripheral foci at transvaginal US are suggestive of endometriomas. MR imaging has high specificity for identifying endometriomas, which are characterized by high signal intensity on T1-weighted images and low signal intensity on T2-weighted images. Correlation of the radiologic imaging features of endometriotic lesions with their laparoscopic appearances may help improve individual proficiency in the radiologic diagnosis of endometriosis.

- Proximal versus ""Distal"" in the Pancreas Dr Yamauchi and colleagues respond(2013) YAMAUCHI, Fernando I.; ORTEGA, Cinthia D.; BLASBALG, Roberto; ROCHA, Manoel S.; CERRI, Giovanni G.; JUKEMURA, Jose
- A premenopausal woman with virilization secondary to an ovarian Leydig cell tumor(2011) FARIA, Andre M.; PEREZ, Ricardo V.; MARCONDES, Jose A. M.; FREIRE, Daniel S.; BLASBALG, Roberto; SOARES JR., Jose; SIMOES, Kleber; HAYASHIDA, Sylvia A. Y.; PEREIRA, Maria A. A.Background. A 33-year-old woman presented to an endocrinology clinic with a 5-year history of secondary amenorrhea. 2 years before presentation, she had noticed progressively worsening signs of virilization. Investigations. Measurement of levels of serum free and total testosterone, androstenedione, dehydroepiandrosterone sulfate and gonadotropins; transvaginal ultrasonography, abdominal and pelvic MRI and (18)F-fluorodeoxyglucose PET imaging. Diagnosis. Virilization secondary to an ovarian Leydig cell tumor. Management. The patient underwent a left salpingo-oophorectomy that confirmed the diagnosis of a unilateral Leydig cell tumor. Complete normalization of androgens and gonadotropin levels was achieved after surgery.
- Liver transplantation(2013) CAIADO, A.; BLASBALG, R.; OGAWA, R.The first whole-liver transplantation in the world was performed in 1963 by Dr Thomas Starzl at the University of Colorado Health Sciences Center in Denver (Bhargava et al. 2011). Survival after liver transplantation has risen considerably over the last decades, due to improvements in surgical techniques, organ conservation, immunosuppressive drugs, and the detection and treatment of postoperative complications (Garcia-Criado et al. 2002). © 2013 Springer-Verlag Berlin Heidelberg.
