Left ventricle size quantification using non-contrast-enhanced cardiac computed tomography - association with cardiovascular risk factors and coronary artery calcium score in the general population: The Heinz Nixdorf Recall Study.
auml;lsch H Abstract BACKGROUND: Increased left ventricular (LV) size is associated with cardiovascular mortality and morbidity. Once non-contrast cardiac computed tomography (CT) is performed for other purposes, information of LV size is readily available. PURPOSE: To determine the association of gated CT-derived LV size with cardiovascular risk factors and coronary artery calcification (CAC) and to describe age- and gender-specific normative values in a general population cohort. MATERIAL AND METHODS: LV area was quantified from non-contrast-enhanced CT in axial, end-diastolic images at a mid-ventricul...

The usefulness of a diagnostic method combining high-resolution CT findings and serum markers for cytomegalovirus pneumonia and pneumocystis pneumonia in non-AIDS patients.
CONCLUSION: The combined use of HRCT findings and serum markers is useful for the diagnosis of CMVP and PCP in non-AIDS patients. The typical HRCT findings for the differential diagnosis included extensive GGA with mosaic pattern in PCP and nodules, nodules with or without the tree-in-bud pattern, and the halo sign in CMVP.

Hemispheric asymmetry measured by texture analysis and diffusion tensor imaging in two multiple sclerosis subtypes.
Abstract BACKGROUND: This paper addresses two subtypes of multiple sclerosis (MS), primary progressive multiple sclerosis (PPMS) and relapsing-remitting multiple sclerosis (RRMS). The separation of PPMS and RRMS is challenging in certain cases. PURPOSE: To quantitatively determine MS subtypes using texture analysis (TA) and diffusion tensor imaging (DTI). MATERIAL AND METHODS: T1-weighted (T1W) magnetic resonance imaging (MRI) and DTI of the left and right brain hemispheres of 17 patients with PPMS and 19 patients with RRMS were studied. Areas of the caudate nucleus and thalamus were investigated as norm...

Assessment of multifocality and axillary nodal involvement in early-stage breast cancer patients using 18F-FDG PET/CT compared to contrast-enhanced and diffusion-weighted magnetic resonance imaging and sentinel node biopsy.
CONCLUSION: For assessment of multifocality in ESBC patients, highly specific results of PET/CT should be taken into account along with DCE-MRI findings. For evaluation of axillary nodal involvement, PET/CT has higher sensitivity, NPV, and accuracy values than DCE-MRI and DWI and may guide a surgical decision to proceed or not to SNB or ALND.

Clinical correlation of a new and practical magnetic resonance grading system for cervical foraminal stenosis assessment.
CONCLUSION: The Kim system showed moderate correlation clinical findings, while the modified Kim system still showed moderate but slightly stronger correlation. In both systems, grade 0 could denote negative neurologic manifestations. Although a considerable number of grade 1 and 2 cases in both systems had PNM, fulfilling the criteria for grades 1 and 2 CNFS, it does not perfectly predict PNM.

Subchondral insufficiency fractures of the knee: review of imaging findings.
Abstract Subchondral insufficiency fracture of the knee (SIFK) is a potentially devastating disorder that may progress rapidly to osteoarthritis with articular surface collapse. It should be suspected in the appropriate clinical setting, as in early stages it is usually indistinct on initial plain radiographs and magnetic resonance imaging is required for a definitive diagnosis. Outcome of SIFK depends on several factors, including the initial subchondral fracture size, patient BMI, degree of osteopenia, as well as early diagnosis and initial treatment. The purpose of this paper is to review the clinical presentat...

Imaging features of subcentimeter hypointense nodules on gadoxetic acid-enhanced hepatobiliary phase MR imaging that progress to hypervascular hepatocellular carcinoma in patients with chronic liver disease.
This study included 109 patients with 135 subcentimeter hypointense nodules (103 hepatocellular carcinomas [HCCs] and 32 benign nodules) on gadoxetic acid-enhanced hepatobiliary phase. For each subcentimeter nodule, the following imaging features were analyzed: (i) hyperintensity on T2-weighted (T2W) image or DWI; (ii) arterial hypervascularization; and (iii) hypointensity on a portal or late phase. Sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of those imaging features for predicting subcentimeter nodules that progressed to hypervascular HCC were evaluated.

Do mammographic tumor features in breast cancer relate to breast density and invasiveness, tumor size, and axillary lymph node involvement?
CONCLUSION: Tumors presenting as an ill-defined mass or calcifications were more common in dense breasts.
