TL;DR: A computer-aided diagnosis (CAD) system based on the fractal analysis is proposed to classify the breast lesions into two classes: benign and malignant and the k-means classification method is used to classify benign tumors from malignant ones.

TL;DR: CT can accurately detect RVD in patients with acute massive pulmonary embolism, however, this result requires confirmation using a larger prospective cohort study.

TL;DR: The training and diagnosis procedure of the proposed system is almost 700 times faster than that of multilayer perception neural networks (MLPs) and helps inexperienced operators avoid misdiagnosis.

TL;DR: For categorizing the presenting neurological symptoms in Takayasu's arteritis and correlating to the imaging findings of cerebral angiography, the angiographies of 27 patients presented with stroke, transient ischemic attack, visual disturbance, and/or dizziness were retrospectively reviewed.

TL;DR: CT is more accurate than chest radiographs for the diagnosis of MCT and for selected patients with inadequacy drainage of the tubes and when chest radiograph is noncontributory, CT scan is recommended to clarify the exact location of chest tubes.

TL;DR: The most frequent brain imaging findings were seen with MR imaging and were more prevalent in NPSLE: high signal intensity focal white matter lesions, infarcts in the cortex and pons, and basal ganglia lesions.

TL;DR: As a less invasive method, percutaneous transcatheter ethanol sclerosis and drainage in the treatment of symptomatic lymphocele is a simple, safe and cost-effective method.

TL;DR: Transcatheter embolization may be the first line of treatment for intrahepatic APF with successful disconnection of hepatic arterial and portal system.

TL;DR: Investigating the value of dynamic contrast-enhanced magnetic resonance imaging in the differentiation of posttreatment fibrosis from recurrent carcinoma found it to be a valuable modality in the differentiate of recurrent tumor from post treatment fibrotic changes of the head and neck.

TL;DR: The results suggest that percutaneous CT-guided biopsy is a useful and reliable tool in the diagnosis and classification of malignant lymphomas in patients without superficial lymphadenopathy and can be considered as an alternative to surgical sampling.

TL;DR: MRI reveals the mass to be hypointense, and an early and persistent enhanced signal is noted following the administration of gadolinium, and the lesion appears markedly hyperintense in T2-weighted fat saturation sequences.

TL;DR: A 44-year-old man with a left perinatal stroke and recurrent refractory epilepsy underwent functional MRI for motor and language mapping to determine if further epilepsy surgery could be performed without loss of language.

TL;DR: Information provided by conventional radiography in the analysis of AC joint OA does not correlate with that provided by MR imaging and MR imaging provides better assessment of the full extent of AC Joint OA and its effect on the underlying RC.

TL;DR: Tumor with lymphatic dilatation on ultrasonography and enhancement of thickened skin and parenchyma on MRI can be useful findings in the diagnosis of inflammatory breast cancer.

TL;DR: Results indicated that contrast-enhanced advanced dynamic flow imaging on US clearly depicted intratumoral vascularity in real time and thus it is useful to diagnose and assess therapeutic efficacy in patients with HCC and metastatic liver tumor.

TL;DR: Thirty-three patients with suspected biliary obstruction were prospectively evaluated with multislice CT cholangiography using thin-slab minimum intensity projection (MinIP) and multiplanar reformation (MPR) to determine its usefulness and to compare with the comparative studies.

TL;DR: 3DUS may reduce the imaging time of the patient, may improve the demonstration of complex anatomy, and has been shown to improve volume assessment, and it holds the potential to improve standardization and documentation, as well as comparison with other sectional imaging.

TL;DR: Papillary carcinoma of the breast is a rare breast carcinoma that can be classified into invasive and noninvasive types.

TL;DR: The preliminary results are encouraging but should also be confirmed by a multicentric based on a large series, and the criteria of inclusion or exclusion must be strictly respected to obtain satisfactory clinical results.

TL;DR: A critical review of the role of computed tomography (CT) and magnetic resonance imaging (MRI) in the diagnosis and therapy of nasopharyngeal cancer and the development of novel technology with CT-scan-simulated 3-D conformal or intensity-modulated radiotherapy (IMRT) planning.

TL;DR: In this paper, CT-guided transforaminal periradicular infiltration with local corticosteroids and anesthetics has been performed for preoperative evaluation of lumbosacral pain and for patients with sciatia.

TL;DR: Collateral vessels were well visualized by CTA, but not by MRA, while conventional angiography revealed leptomeningeal collateral vessels that were filled in a retrograde fashion.

TL;DR: The stomach and pancreatic lesions were demonstrated as hypervascular nodules on computed tomography (CT), more conspicuous on arterial phase images, and early phase post-contrast imaging might improve the detection of extraosseous myeloma.

TL;DR: It is demonstrated that the neuronal degradation or loss was observed in all gliomas and higher-grade glioma was correlated with higher Cho/Cr ratio, indicating a significant dependence of Cho levels on malignancy ofgliomas.

TL;DR: Over an 8-year period, ultrasonography (US)-guided core biopsy of the salivary gland was performed in 37 patients using an 1l-mm-throw 18-gauge automated biopsy system and the sensitivity, specificity, and accuracy were 75.0, 96.6, and 91.9%, respectively.

TL;DR: A case of a patient in whom the early use of specific imaging and of proper aggressive surgical intervention did not allow the elimination of a fatal outcome, and the cervicothoracic scanning is the ideal procedure leading to the diagnosis, the localization of the infectious sites, and to the demonstration of an abscess and the presence of air in the mediastinum.

TL;DR: The case of a 36-year-old woman in whom the initial MRI findings were thought to be consistent with only an arachnoid cyst compressing the spinal cord is presented, and a repeat MRI study was interpreted as being compatible with a transdural spinal cord herniation.

TL;DR: In this article, the authors compared the effectiveness of functional MRI and intraoperative cortical stimulation (ICS) in planning cortex-saving neurosurgical interventions, and found that the spatial correlation between fMRI and ICS for the sensorimotor cortex is very high.
