Are the recorded data of flash glucose monitoring systems influenced by radiological examinations?

The FreeStyle Libre Pro flash glucose monitoring system is easy to use in diabetes care. However, the influence of radiological examination on recorded data has not been reported. The sensor should be removed prior to examinations involving strong magnetic or electromagnetic radiation.

Influence of arm position and respiration technique during liver examinations on the detectability of mammary lesions.

During liver computed tomography (CT), scanning is performed with the raised arm position and an inhalation technique. However, for liver magnetic resonance imaging (MRI), the arms are placed at the sides of the body and an exhalation technique is used. This study was aimed at evaluating the effect that the patient's arm position and respiration technique had on the ability to detect mammary glands in the scan range to discover unexpected mammary lesions during the liver MRI examination.

Hepatobiliary phase images using gadolinium-ethoxybenzyl-diethylenetriamine penta-acetic acid-enhanced MRI as an imaging surrogate for the albumin-bilirubin grading system.

Objectives: To clarify the correlation between hepatobiliary phase (HBP) images using gadolinium-ethoxybenzyl-diethylenetriamine penta-acetic acid (Gd-EOB-DTPA) and albumin-bilirubin (ALBI) grading system.

Materials And Methods: We evaluated 220 consecutive patients who underwent liver magnetic resonance imaging with Gd-EOB-DTPA. Quantitative liver-spleen contrast ratio (Q-LSC) was calculated in HBP images approximately 20min after Gd-EOB-DTPA administration.

A novel method for evaluating enhancement using gadolinium-ethoxybenzyl-diethylenetriamine penta-acetic acid in the hepatobiliary phase of magnetic resonance imaging.

To investigate whether quantitative liver-portal vein contrast ratio (Q-LPC) can be used as a substitute for quantitative liver-spleen contrast ratio (Q-LSC) in the hepatobiliary phase (HBP) contrasting degree. Q-LSC and Q-LPC were calculated in HBP images that were obtained approximately 20 min after gadolinium-ethoxybenzyl-diethylenetriamine penta-acetic acid injection, and relationship between them was evaluated. A very strong correlation was observed between Q-LSC and Q-LPC with respect to Child-Pugh class.

Pertuzumab, trastuzumab and docetaxel reduced the recurrence of brain metastasis from breast cancer: a case report.

The CLEOPATRA trial reported the survival benefit of pertuzumab with trastuzumab plus docetaxel in HER2-positive metastatic breast cancer patients. However, there are a few case reports concerning the effects of a pertuzumab-containing regimen on brain metastases. A 55-year-old woman, who underwent curative surgery for breast cancer after neoadjuvant chemotherapy 5 years previously, developed repeated solitary brain metastasis in her right occipital lobe.

Comparative study of vascular enhancement on post-contrast CT using three dosages of iodinated contrast media for the aim of detecting brain metastasis in patients with lung cancer.

Objective: A prospective double-blind randomized study was performed to compare the contrast of vascular enhancement using three dosages of iodinated contrast media for a possible metastatic lesion in the brain.

Materials And Methods: Sixty-six patients with lung cancer received brain computed tomography (CT) with intravenous administration of iodinated contrast medium (CM). The patients were randomly assigned to receive one of the three types of CM: 30 g iodine, 24 g iodine, and 15 g iodine.

Benign or malignant?: differentiating breast lesions with computed tomography attenuation values on dynamic computed tomography mammography.

Objective: To evaluate enhancement effects of breast lesions with dynamic computed tomography (CT) and to determine characteristics to aid in differential diagnosis of benign and malignant lesions.

Methods: One hundred seventy-six women underwent preoperative dynamic CT, in which they were scanned with rapid injection of contrast media (3 mL/s) after 30 seconds and 2 minutes (early and delayed phases, respectively). The CT values and enhancement patterns of malignant lesions (n = 154) were compared with those of benign lesions (n = 22), and the cut point of CT values with the best validity was analyzed.

Accumulation of 99mTc-PMT in renal metastasis of hepatocellular carcinoma.

We describe here a case in which 99mTc-Sn-N-pyridoxy-5-methyltryptophan (99mTc-PMT) scintigraphy was useful in diagnosing renal metastasis of hepatocellular carcinoma (HCC). A 62-year-old man who had undergone hepatectomy for HCC presented 6 years after initial diagnosis with left flank pain and was found on CT and MRI to have a tumor in the left kidney. Hepatobiliary scintigraphy using 99Tc-PMT was performed, and 99mTc-PMT accumulation was found in the tumor.

A simplified double-injection method to quantify cerebral blood flow and vascular reserve using iodine-123 IMP-SPECT.

Unlabelled: We developed and evaluated a simplified double-injection method for iodine-123 N-isopropyl-p-iodoamphetamine (IMP) to quantify regional cerebral blood flow (rCBF) twice in a single SPECT session. The method enabled rapid calculations of rCBF with five 10-minute SPECT scans, a fixed distribution volume (Vd), and one-point arterial blood sampling to calibrate a standard input function (SIF).

Methods: Sixty neurological patients were examined to measure rCBF twice in a single session of IMP-SPECT.
