Intravoxel Incoherent Motion Diffusion-Weighted Imaging for Quantitative Differentiation of Breast Tumors: A Meta-Analysis.

The diagnostic performance of intravoxel incoherent motion diffusion-weighted imaging (IVIM-DWI) in the differential diagnosis of breast tumors remains debatable among published studies. Therefore, this meta-analysis aimed to pool relevant evidence regarding the diagnostic performance of IVIM-DWI in the differential diagnosis of breast tumors. Studies on the differential diagnosis of breast lesions using IVIM-DWI were systemically searched in the PubMed, Embase and Web of Science databases in recent 10 years.

The purpose of this study was to investigate the ability to detect breast abnormalities using non-contrast BCBCT and contrast-enhanced BCBCT (BCBCT and CE-BCBCT) compared to ultrasound (US) and digital mammography (MG).

Materials And Methods: A prospective study was performed from May 2012 to August 2014.

Hypertrophic adenoids in patients with nasopharyngeal carcinoma: appearance at magnetic resonance imaging before and after treatment.

Introduction: Patients with nasopharyngeal carcinoma (NPC) sporadically develop abnormal adenoids. Nasopharyngeal adenoids are usually included in the gross tumor volume (GTV) but may have different therapeutic responses than tumor tissue. Therefore, distinguishing adenoids from tumor tissue may be required for precise and efficient chemoradiotherapy and radiotherapy.

CT Characterization of Duodenal Gastrointestinal Stromal Tumors.

Objective: Diagnosis and staging of duodenal gastrointestinal stromal tumors (GISTs) by noninvasive imaging is critical for effective treatment, but the imaging features of duodenal GISTs remain largely undefined because of their rarity. The purpose of this article was to characterize duodenal GISTs using CT.

Materials And Methods: Thirty-four patients with duodenal GISTs were analyzed by clinical symptom evaluation, pathologic examination, and CT in this retrospective study.

Nasopharyngeal carcinoma patients with retropharyngeal lymph node metastases: a minimum axial diameter of 6 mm is a more accurate prognostic predictor than 5 mm.

Abnormal baseline brain activity in patients with HBV-related cirrhosis without overt hepatic encephalopathy revealed by resting-state functional MRI.

Neurocognitive dysfunction of varying degrees is common in patients with hepatitis B virus-related cirrhosis (HBV-RC) without overt hepatic encephalopathy (OHE). However, the neurobiological mechanisms underlying these dysfunctions are not well understood. We sought to identify changes in the neural activity of patients with HBV-RC without OHE in the resting state by using the amplitude of low-frequency fluctuation (ALFF) method and to determine whether these changes were related to impaired cognition.

Nasopharyngeal tuberculosis: CT and MRI findings in thirty-six patients.

Purpose: Tuberculosis is uncommon in the nasopharynx. The purpose of this study was to investigate the CT and MRI features of 36 cases of tuberculosis in this area.

Materials And Methods: CT (n=15) and MRI (n=21) scans from 36 patients with histologically proved tuberculosis of the nasopharynx were reviewed by two experienced radiologists, paying particular attention to the lesions' distribution, location, extent, size, internal architecture, pattern, and degree of enhancement, and cervical lymphadenopathy.

CT and MRI of radiation-induced sarcomas of the head and neck following radiotherapy for nasopharyngeal carcinoma.

Aim: To investigate the radiological findings of head and neck radiation-induced sarcomas (RISs) following radiotherapy for nasopharyngeal carcinoma (NPC).

Materials And Methods: Fifty-nine patients with RISs were identified. Imaging characteristics on computed tomography (CT) and magnetic resonance imaging (MRI), including lesion location, extent, size, margin, internal architecture, pattern, and degree of enhancement, together with patient characteristics at NPC diagnosis and latency periods, were reviewed.

Hepatic angiomyolipoma: CT and MR imaging findings with clinical-pathologic comparison.

Objective: The objective of this study is to evaluate the clinical, pathologic, and computed tomography (CT) and/or magnetic resonance imaging (MRI) findings of hepatic angiomyolipoma (HAML) and to improve the diagnostic efficacy of the tumor.

Materials And Methods: Clinical, pathologic, and imaging findings were retrospectively evaluated in 18 patients with HAML. Two patients underwent both CT and MRI, ten underwent CT alone, and six underwent MRI alone.

Solid neuroendocrine breast carcinoma: mammographic and sonographic features in thirteen cases.

This study aimed to determine and quantitate the mammographic and sonographic characteristics in 13 cases of solid neuroendocrine breast carcinoma (NEBC) and to analyze the association of radiological findings with the clinical and histopathologic findings. The clinical data and imaging findings of 13 female patients with histologically confirmed solid NEBC were reviewed. Imaging data were evaluated by two radiologists for a consensual diagnosis.

Characterizing the clustered microcalcifications on mammograms to predict the pathological classification and grading: a mathematical modeling approach.

In this study, we explore a mathematical model to characterize the clustered microcalcifications on mammograms for predicting the pathological classification and grading. Our database consists of both retrospective cases (78 cases) and prospective cases (31 cases) with pathologically diagnosed clusters of microcalcifications on mammograms. The microcalcifications were divided into four grades: grade 0, benign breast disease including mastopathies (n = 12) and fibroadenomas (n = 20); grade 1, well-differentiated infiltrating ductal carcinoma (n = 12); grade 2, moderately differentiated infiltrating ductal carcinoma (n = 38); grade 3, poorly differentiated infiltrating ductal carcinoma (n = 27).

Radiocolloid in combination with methylene dye localization, rather than wire localization, is a preferred procedure for excisional biopsy of nonpalpable breast lesions.

Background: Wire localization (WL) is traditionally performed before excisional biopsy for patients with nonpalpable breast lesions, but it has several disadvantages. Our current study examines whether the method of radiocolloid combined with methylene dye localization (RCML) has an advantage over WL.

Materials And Methods: From August 2006 to May 2009, 157 patients with nonpalpable breast lesions classified as BI-RADS category 5 were enrolled in our study.

Significance of methylene blue dye for localization biopsy of nonpalpable breast lesions.

Background And Objective: With advances in mammographic equipment and techniques, more and more nonpalpable breast lesions have been detected. This study was to investigate the application of methylene blue dye for localized biopsy to diagnose nonpalpable breast lesions.

Methods: In total 138 patients with suspicious malignant, nonpalpable breast lesions between August 2002 and October 2006 were enrolled.

[CT features of adrenal cortical adenoma: a report of 109 cases].

Background & Objective: Adrenal cortical adenoma (ACA) is a common disease, and can be diagnosed easily with CT examination. However, some atypical adenomas are likely to be misdiagnosed. This study was to evaluate the common and uncommon CT features of ACA to improve the diagnostic accuracy.

[Clinical evaluation of three methods of fine-needle aspiration, large-core needle biopsy and frozen section biopsy with focus staining for non-palpable breast disease].

Background & Objective: Early detection of breast cancer is crucial to improve the therapeutic effect and to increase the survival rate. However, it is difficult because breast cancer in early stage was usually occult, impalpable, and could not be detected by laboratory test. This study was designed to compare the effectiveness of three methods for diagnosis of non-palpable breast cancer.

[Comparison of therapeutic effects between transcatheter arterial chemoembolization and transcatheter arterial-portal venous double chemoembolization in treatment of moderate and advanced stages of primary liver carcinoma].

Background & Objective: Many clinic data showed that it is difficult to control primary liver carcinoma (PLC) by transcatheter arterial chemoembolization (TACE) alone due to existence of double blood supply of liver by hepatic artery and portal vein. This study was designed to evaluate the efficacy of transcatheter arterial chemoembolization combined with portal venous chemoembolization (PVCE) in the treatment of moderate and advanced stages of PLC.

Methods: Fifty-eight cases of moderate and advanced stages of PLC were treated with a combination of TACE and PVCE (TACE/PVCE group) and 118 patients with moderate and advanced stages of PLC were treated with TACE alone (TACE group).
