In patients undergoing radiotherapy for localized prostate cancer, dose–volume histograms and clinical variables were examined to search correlations between radiation treatment planning parameters late rectal bleeding. We analyzed 129 with cancer who managed from 2002 2010 at our institution. They treated 3D conformal therapy (3D-CRT, 70 Gy/35 fractions, 55 patients) or intensity-modulated (IMRT, 76 Gy/38 74 patients). All plans retrospectively reconstructed, of the rectum generated, doses...
To analyze diagnostic features on images of congenital arteriovenous malformation (AVM) the pancreas, we analyzed findings in six patients with disease, using gray-scale ultrasonography (US), color Doppler US, computed tomography, and angiography previously reported cases. AVM characteristic were multiple, small hypoechoic nodules mosaic appearance lesion pulsatile wave form portal vein conglomerated nodular enhancement early CT, a racemose network angiography. Five underwent surgery, all...
To determine whether superparamagnetic iron oxide-enhanced magnetic resonance imaging (SPIO-MRI) could replace intravenous contrast-enhanced spiral CT (iv-CT) and during arterial portography (CTAP) combined with hepatic angiography (CTHA) in the diagnosis of liver metastases from colorectal carcinomas.Twenty-six adult patients were studied preoperatively by means iv-CT, CTAP/CTHA, SPIO-MRI. Preoperative diagnoses using SPIO-MRI compared intraoperative pathological findings resected...

To correlate the imaging and pathological features to discuss therapeutic modalities prognosis of malignant lymphoma originating in parotid gland, which is relatively rare.The subjects were five patients with gland. Three two stage I II, respectively. CT examination was applied all, whereas only one case examined by MRI. All treated radiotherapy following surgery or chemotherapy. underwent combination chemotherapy, such as MACOP-P VEPA, surgery.Although gland histologically described...
A paradoxical reaction during antituberculosis treatment is defined as the worsening of pre-existing tuberculosis lesions or appearance a new lesion in patients whose clinical symptoms improved with treatment. The median onset time to development response has been reported be about 60 days after start We report case patient presenting psoas abscess nine months To best our knowledge, this manifestation not previously reported. 23-year-old Japanese man presented hospital lower abdominal pain....
Background and Study Aims: No studies comparing virtual computed tomography (CT) cholangioscopy of the common bile duct compared with fiberoptic are available. The aim our study was to evaluate feasibility CT duct.
A 32 year old woman was referred because of secondary amenorrhea, hirsutism, and voice deepening.The blood testosterone level markedly high. transvaginal ultrasound revealed a small region in the left ovary, but whether or not it tumor unclear. Therefore, selective ovarian venous sampling performed. Consequently, selectively increased sample that taken from vein, successfully localized, laparoscopic oophorectomy Although ovary appeared to be normal at laparoscopy, androgen-secreting located...
Abstract A 37‐year‐old pregnant woman who had undergone three previous cesarean sections was diagnosed as having placenta percreta. We decided to perform hysterectomy with bilateral common iliac artery balloon occlusion (CIABO). The duration of surgery 2 h and min total estimated blood loss 2600 mL. Surgery completed without any surgical complications, but the pulse oximeter waveform left leg became undetectable during surgery. immediately performed angiography after closure laparotomy found...
A 71 year old man was diagnosed to have enlargement of abdominal aortic aneurysm due type 2 endoleak two years after endovascular repair (EVAR). 3D-CT demonstrated a that originated from the superior mesenteric artery fed inferior and right iliolumbar flowed into 4th lumbar artery. Transarterial embolization performed by means N-butyl-2-cyanoacrylate (NBCA). After treatment, he suffered ischemic colitis extended sigmoid colon descending colon. Conservative treatment mainly performed,...
Purpose: To evaluate the histopathological features of experimental aneurysms embolized with bare platinum, fibered, and bioactive coils.Material methods: Twelve were constructed in three swine. The divided into four groups using a platinum coil alone (P group, n = 2), (B combination fibered coils (F/P 4) (F/B 4). Histopathological data for all recorded at 63 days analyzed terms neointima formation, fibrosis, foreign-body giant-cell infiltration, organization.Results: Fibrosis was...
To elucidate the characteristics of 3 D frame coils and identify optimal coil for visceral aneurysms.Using a vascular model, we compared postembolization distribution repulsive force three coils: Guglielmi detachable (GDC; stock wire diameter, 0.004 in; primary 0.015 in), Target XL (0.003, 0.014), XXL 0.017). Additionally, area, roundness, center gravity were quantitatively compared. The was measured by compressing vessel model with digital gauge.There no significant differences in area...
