Using a Motion Sensor-Equipped Smartphone to Facilitate CT-Guided Puncture.

Purpose: To demonstrate the use of "Smart Puncture," a smartphone application to assist conventional CT-guided puncture without CT fluoroscopy, and to describe the advantages of this application.

Materials And Methods: A puncture guideline is displayed by entering the angle into the application. Regardless of the angle at which the device is being held, the motion sensor ensures that the guideline is displayed at the appropriate angle with respect to gravity.

Magnetic resonance evaluation of brain metastases from systemic malignances with two doses of gadobutrol 1.0 m compared with gadoteridol: a multicenter, phase ii/iii study in patients with known or suspected brain metastases.

Objectives: To determine the efficacy and safety of 2 doses of gadobutrol 1.0 M (0.1 and 0.

Suspicious calcifications in benign breast lesions: a radio-pathologic correlation.

Background: Breast cancer screening by mammography (MMG) has recently increased in Japan. Suspicious lesions are therefore being detected more and more by MMG and the number of benign biopsies is increasing. It is thus important to examine which pathologically benign lesions were read as suspicious on MMG to reduce the number of biopsies in the case of benign breast lesions.

Determination of indication for sentinel lymph node biopsy in clinical node-negative breast cancer using preoperative 18F-fluorodeoxyglucose positron emission tomography/computed tomography fusion imaging.

Objective: Sentinel node biopsy (SNB) is indicated for axillary lymph node metastasis-negative cases (N0), but clarification of the indication may increase treatment efficiency. Fluorine-18-labeled 2-fluoro-2-deoxy-D-glucose positron emission tomography (FDG-PET) may have a high positive predictive value in diagnosis of axillary lymph node metastasis.

Methods: Ninety-two breasts/axillae were analyzed retrospectively in 90 patients (median age 54.

Relation between cancer cellularity and apparent diffusion coefficient values using diffusion-weighted magnetic resonance imaging in breast cancer.

Purpose: The purpose of this study was to examine the relation between cancer cellularity and the apparent diffusion coefficient (ADC) value using diffusion-weighted magnetic resonance imaging in breast cancer.

Materials And Methods: The subjects were 27 women who had undergone operation for breast cancer. There were 27 breast cancer lesions, 24 of which were invasive ductal carcinoma (IDC) and 3 of which were noninvasive ductal carcinoma (NIDC).

Contrast-enhanced CT evaluation of clinically and mammographically occult multiple breast tumors in women with unilateral early breast cancer.

Background: Magnetic resonance imaging mammography is performed to determine the extent of lesions and to detect occult lesions, but preoperative diagnosis by breast computed tomography (CT) is less common.

Methods: We performed a retrospective study of detection of mammographically occult multiple lesions using breast CT. The subjects were 407 female patients (median age: 56 years old; median tumor size: 1.

Comparison of breast cancer detection by diffusion-weighted magnetic resonance imaging and mammography.

Purpose: Breast cancer-detecting ability of diffusion-weighted magnetic resonance imaging (DW-MRI) was investigated by comparing the breast cancer detection rates of DW-MRI and mammography (MMG).

Materials And Methods: The subjects were 48 women who had breast cancer (53 cancer lesions) who underwent DW-MRI before surgery. Altogether, 41 lesions were invasive ductal carcinoma (IDC), 7 were noninvasive ductal carcinoma (NIDC) and 5 were "others.

Pulsating renal blood flow distribution measured using power Doppler ultrasound: correlation with hypertension.

Arterial compliance is associated with the first stage of hypertension and atherosclerosis. We propose here a compliance index, which measures pulsating renal blood flow distribution using a power Doppler ultrasound (US). We assessed the relationship between the compliance index and blood pressure and between the compliance index and risk factors of atherosclerosis.
