    Department of Internal Medicine, Pratumtani Hospital, 7 Ladlumkaew, Muang District, Pratumtani 12000, Thailand.
    Preoperative staging of rectal cancer using magnetic resonance imaging (MRI) has become an important component of clinical management. Although MRI is the modality of choice for rectal cancer diagnosis and staging, there are certain inherent potential pitfalls that radiologists need to recognize in order to avoid imaging misinterpretation, including choice of MRI protocol; choice of MRI technique; potential mimickers of rectal cancer; mucinous rectal tumor; differentiation between extramural tumor invasion and desmoplastic reaction; differentiation between low rectal cancer and anal cancer; problems relating to nodal involvement, peritoneal reflection, and mesorectal fascia invasion; and, challenges associated with restaging, post-treatment changes, and complications. The aim of this article was to heighten radiologist awareness of these potential pitfalls in order to improve diagnosis, decision-making, and patient outcomes. Read More

    Radiology Harvard Medical School, Founder Bresat Imagning Division Massachusetts General Hospital, 20 Manitoba Road, Waban, MA 02468, United States. Electronic address:
    It is important to understand the history of breast cancer screening to better understand the continuing effort to reduce access to screening. Since the randomized, controlled trials have shown a statistically significant mortality reduction for women ages 40-74, the appropriate threshold for initiating screening is age 40 with no data to support the use of the age of 50 as a threshold for screening. All women are at risk for developing breast cancer and all women should have access to screening. Read More

    Clin Imaging 2018 Jan - Feb;47:v-vii. Epub 2017 Nov 21.
    Creating a successful quality and patient safety program requires a multifaceted approach that systematically reviews overall systems and processes, but also creates a standardized framework for evaluating individual practitioner performance on a routine basis. There are two required elements of competency assessment that are typically tied to the hospital credentialing process: ongoing professional practice evaluation (OPPE) and focused professional practice evaluation (FPPE). Each of these processes are mandated by the Joint Commission, and form an important cornerstone for ensuring adequate physician performance and knowledge base. Read More

    Comparative diagnostic accuracy of dual-energy CT myocardial perfusion imaging by monochromatic energy versus material decomposition methods.
    Clin Imaging 2017 Nov 11;50:1-4. Epub 2017 Nov 11.
    Dalio Institute of Cardiovascular Imaging, Department of Radiology, NewYork-Presbyterian Hospital and Weill Cornell Medicine, New York, NY, USA. Electronic address:
    Purpose: To compare the diagnostic value of monochromatic and material decomposition (MD) dual- energy computed tomography (DECT) imaging for the evaluation of ischemia.

    Methods: Patients with suspected coronary artery disease underwent rest-stress DECT and SPECT perfusion imaging. DECT images were reconstructed between 40 and 140keV and through MD of iodine/muscle. Read More

    Case of urethral duplication seen by voiding urosonography.
    Clin Imaging 2017 Dec 1;49:106-110. Epub 2017 Dec 1.
    Department of Radiology, Boston Children's Hospital, Harvard Medical School, 300 Longwood Ave, Boston, MA 02115, USA. Electronic address:
    A 3-month-old premature male infant with imperforate anus and hypospadias underwent contrast-enhanced voiding urosonography (ceVUS) followed by voiding cystourethrography (VCUG). Images from the ceVUS demonstrated a distinct linearity arising dorsally from the posterior urethra that partially opacified with contrast. VCUG confirmed a urethral duplication. Read More

    Percutaneous low-dose CT-guided lung biopsy with an augmented reality navigation system: validation of the technique on 496 suspected lesions.
    Clin Imaging 2017 Dec 2;49:101-105. Epub 2017 Dec 2.
    Department of Diagnostic and Interventional Radiology, Università Campus Bio-Medico di Roma, Via Alvaro del Portillo, 200, 00128 Roma, Italy. Electronic address:
    Purpose: To validate a CT-navigation system during percutaneous lung biopsy (PLB).

    Methods: Four hundred-ninety-six patients underwent low-dose CT-guided PLB. Lesion diameter (LD), procedural time (PT), histologic validity, lesion distance from pleural surface (DPS), needle distance travelled during procedure (DTP), complications and radiation exposure were recorded.

    The predictive value of computed tomography in the detection of reflux esophagitis in patients undergoing upper endoscopy.
    Clin Imaging 2017 Nov 24;49:97-100. Epub 2017 Nov 24.
    2nd Department of Medicine, Department of Cardiovascular Medicine, First Faculty of Medicine, Charles University and General University Hospital in Prague, Czech Republic.
    Background: Reflux esophagitis (RE) may mimic symptoms requiring cross-sectional imaging.

    Methods: From 565 patients who had CT and esophagogastroduodenoscopy within four days apart, CT scans of 72 patients with RE confirmed by esophagogastroduodenoscopy and 108 matched patients without RE were evaluated for distal esophageal wall characteristics.

    Results: In RE patients the distal esophageal wall thickness was greater (5. Read More

    Clin Imaging 2017 Nov 24;49:89-96. Epub 2017 Nov 24.
    Department of Radiology, University of North Carolina at Chapel Hill, NC, USA. Electronic address:
    Purpose: To describe MRI features of multiple Focal Nodular Hyperplasia (FNHs).

    Methods: 40 consecutive subjects (37 females, mean age, 38.8years) were included. Read More

    Artificial intelligence and deep learning - Radiology's next frontier?
    Clin Imaging 2017 Nov 18;49:87-88. Epub 2017 Nov 18.
    The University of Texas MD Anderson Cancer Center, 1515 Holcombe Blvd., Unit 1350, Houston, TX 77030, United States.
    Tracing the use of computers in the radiology department from administrative functions through image acquisition, storage, and reporting, to early attempts at improved diagnosis, we begin to imagine possible new frontiers for their use in exam interpretation. Given their initially slow but ultimately substantial progress in the noninterpretive areas, we are left desiring and even expecting more in the interpretation realm. New technological advances may provide the next wave of progress and radiologists should be early adopters. Read More
