Objective: To evaluate whether the histopathological differentiation and expression of vascular endothelial growth factor (VEGF) hepatocellular carcinoma (HCC) do show correlation with apparent diffusion coefficient (ADC) value on diffusion-weighted imaging (DWI). Materials Methods:Twenty-seven HCCs from 27 patients who had undergone preoperative liver MRI (1.5T) surgical resection were retrospectively reviewed.DWI was obtained a single-shot, echo-planar sequence in axial plane (b values: 0...
To evaluate the value of apparent diffusion coefficient (ADC) histogram analysis for predicting tumor recurrence in patients with uterine cervical cancer treated chemoradiation therapy (CRT).Our institutional review board approved this retrospective study and waived informed consent from each patient. Forty-two (mean age, 56 ± 14 years) biopsy-proven squamous cell carcinoma who underwent both pre-treatment pelvic magnetic resonance imaging a 3.0 T scanner concurrent CRT were included. All...
To compare the effectiveness of radiofrequency ablation (RFA) combined with transcatheter arterial chemoembolization (TACE) surgical resection in patients a single hepatocellular carcinoma (HCC) ranging from 2 to 5 cm.The study participants were enrolled over period 29 months and comprised 37 therapy group 47 group. RFA was performed day after TACE, by open laparotomy. The two groups compared respect length hospital stay, rates major complication, recurrence-free overall survival.Major...
Non-invasive approach other than conventional endoscopy could be effectively used for screening and monitoring esophageal variceal bleeding (EVB). To retrospectively investigate the role of four-dimensional (4D) flow magnetic resonance imaging (MRI) as an add-on tool to predicting EVB in cirrhotic patients with varices (EVs). A cohort 109 EVs was divided into four groups: = negative red color [RC] sign, no EVB, n 60; B RC 13; C positive 10; D 26. All underwent laboratory assessments 4D MRI...
A sclerosing stromal tumor of the ovary is an extremely rare benign tumor; it usually found during second and third decades life. Patients present with pelvic pain or a palpable abdominal mass. Hormonal effects such as masculinization are uncommon. Here, 11-year old premenarchal girl presented deepening voice. In addition, clitoromegaly hirsutism male suprapubic hair pattern were observed. The laboratory findings showed that testosterone level was elevated to 3.67 ng/mL, andostenedione above...
The purpose of this study was to establish a minimally invasive and reproducible protocol for estimating the gastrointestinal (GI) transit time in mice using barium radiopaque markers.Twenty 5- 6-week-old Balb/C female weighing 19-21 g were used. animals divided into three groups: two groups that received loperamide control group. group (n = 10) administered physiological saline (1.5 mL/kg) orally. I II 5 mg/kg 10 orally, respectively. Thirty minutes after receiving or loperamide, 80 µL...
Objective: To compare gadoxetic acid injection rates of 0.5 mL/s and 1 for hepatic arterial-phase magnetic resonance (MR) imaging. Materials Methods:In this prospective study, 101 consecutive patients with suspected focal liver lesions were included randomly divided into two groups.Each group underwent dynamic MR imaging using a 3.0-T scanner after an intravenous at either (n = 50) or 51).Arterial phase images analyzed blinding the rates.The signal-to-noise ratios (SNRs) liver, aorta, portal...
We report an uncommon case of solitary, small hepatic angiosarcoma that was initially considered as a hemangioma. present the imaging findings, with emphasis on initial and follow-up CT MR well more suggestive findings than those
Objective: To explore the features that predict size increase and development of potential malignant in incidentally detected, unilocular cystic pancreatic lesions (CPLs) less than 3 cm diameter, during subsequent follow-up.Materials Methods: We retrieved data patients diagnosed with CPLs diameter period from November 2003 through December 2014, using a computerized search.All serial CT MR images were analyzed to identify number, size, location CPLs; dilatation main duct; occurrence...
We report here on a case of localized lymphoid hyperplasia the pancreas in 70-year-old man which manifested as double lesions (uncinate process and tail) organ.The were incidentally detected hypoechoic ultrasonography they appeared delayed enhancing contrast-enhanced dynamic CT MRI.Total pancreatectomy was performed, because malignant tumor could not be excluded according to preoperative imaging studies endoscopic ultrasound-guided biopsy failed.Pathology revealed hyperplasia.The patient had...
Liver cirrhosis (LC) can develop hepatocellular carcinoma (HCC). However, noninvasive early diagnosis of HCCs in the cirrhotic liver is still challenging. We aimed to quantify hepatic metabolites normal control (NC), without HCC, with HCC (CLH), and early-stage groups using proton magnetic resonance spectroscopy (1H-MRS) a long echo-time (TE) assess potential association between levels these four aging enzymatic activity. Thirty NCs, 30 viral hepatitis-induced LC patients were included this...
Objective: To evaluate the effectiveness of ultrasound-guided radiofrequency (RF) ablation in patients with incompletely treated hepatocellular carcinoma (HCC) after transcatheter arterial chemoembolization (TACE) and to possible prognostic factors for this therapy.Subjects Methods: Thirty nine single HCC (≤ 5 cm) TACE were RF ablation.All evaluated complete tumor rate, local recurrence-free overall survival complications.Local rate calculated using Kaplan-Meier method.The analyzed Cox...
Hepatic abscesses are known to present with various imaging findings according the degree of maturation and internal contents.1 abscess rarely mimics hepatic neoplasm such as HCC. As evidenced by our case, if there no clinical laboratory suggestive abscess, that presents findings, early arterial enhancement delayed washout, mosaic pattern enhancement, well-defined tumoral capsule could be hardly differentiated from
Primary angiosarcomas of the kidney are very rare, but highly aggressive tumors showing poor prognosis. Patients frequently complain flank pain, hematuria, or a palpable mass. We present case primary renal angiosarcoma occurring in 61-year-old man. CT images depicted huge exophytic mass (16 cm diameter) right kidney, exhibiting extensive hemorrhage. The showed centripetal peripheral nodular enhancement on dynamic contrast-enhanced images. Furthermore, MR imaging revealed tangled mesh tumor...
Abstract To identify the gadoxetic acid (GA)-enhanced magnetic resonance imaging (MRI) and laboratory findings that enable prediction of treatment response disease-free survival (DFS) after first session drug eluting bead transarterial chemoembolization (DEB-TACE) in patients with hepatocellular carcinoma (HCC). A total 55 who underwent GA-enhanced MRI DEB-TACE from January 2014 to December 2018 were included. All features reviewed by two radiologists. Treatment was evaluated according...
Portal vein thrombosis (PVT) is commonly associated with liver cirrhosis, irrespective of the presence hepatocellular carcinoma (HCC).Given that malignant PVT a poor prognostic factor in patients HCC, it important to differentiate from benign PVT.Because has been reported be contiguous parenchymal most cases, alone indicates entity.We report case patient rapid progression mimicking but without definite HCC on imaging modalities.
