  • 15 O-H2O PET/CT as a tool for the quantitative assessement of early post-radiotherapy changes of heart perfusion in breast carcinoma patients. [Journal Article]
  • BJBr J Radiol 2018 Feb 22; :20170653
  • Żyromska A, Małkowski B, … Makarewicz R
  • CONCLUSIONS: 15O-H2O PET/CT is safe and effective for the early detection and quantitative analysis of subclinical post-radiotherapy changes in heart perfusion in breast cancer patients. The LV segments supplied by the LAD are the main site of MBF changes. A minimum radiation dose deposited in the LAD may be a predictor of radiation-induced heart toxicity. Advances in knowledge: This is the first time that 15O-H2O PET/CT has been used to assess MBF after radiotherapy and the first granular description of the distribution of blood flow changes after breast cancer radiotherapy.
  • Doses from cervical spine computed tomography (CT) examinations in the UK. [Journal Article]
  • BJBr J Radiol 2018 Feb 22; :20170834
  • Holroyd JR, Edyvean S
  • CONCLUSIONS: The rounded third quartile value of the mean dose distributions from this study were a CT dose index (CTDIvol) of 20 mGy and a dose-length product of 440 mGy cm as quoted for a 32 cm body phantom. These are significantly higher than those in the 2011 Public Health England CT dose survey when adjusted for phantom size. It is suggested that the existing national diagnostic reference levels for cervical spine CT should be amended, both with the new values and also to quote according to the 32 cm phantom. Advances in knowledge: Proposed new national diagnostic reference levels are presented for cervical spine CT examinations.
  • A novel minimally invasive method of successful tissue glue injection in patients with iatrogenic pseudoaneurysm. [Journal Article]
  • BJBr J Radiol 2018 Feb 22; :20170538
  • Kurzawski J, Janion-Sadowska A, Sadowski M
  • CONCLUSIONS: Embolization of iatrogenic pseudoaneurysm using tissue glue seems to be an effective technique for the treatment of this complication. It might be considered as a treatment option in case of unsuccessful primary repair by means of thrombin injection orhemorrhagic shock due to rapid aneurysm progression. Advances in knowledge: Patients with multiple recanalizations and those with dynamically enlarging pseudoaneurysm or rapidly progressing anaemia are at risk of life-threatening bleeding. An ultrasound-guided tissue glue injection, a novel method for the treatment of femoral artery pseudoaneurysm, might be considered as a treatment option especially in case of primary thrombin injection failure.
  • Quantitative analysis of enhanced malignant and benign lesions on contrast-enhanced spectral mammography. [Journal Article]
  • BJBr J Radiol 2018 Feb 16; :20170605
  • Deng CY, Juan YH, … Ng SH
  • CONCLUSIONS: Despite variations in the degree of tumoural angiogenesis, quantitative analysis of the breast lesions on CESM documented the malignancies had distinctive stronger enhancement and depressed relative enhancement patterns than benign lesions. Advances in Knowledge: To our knowledge, this is the first study evaluating the feasibility of quantifying lesion enhancement on CESM. The quantities of enhancement were informative for assessing breast lesions in which the malignancies had stronger enhancement and more relative depressed enhancement than the benign lesions.
