3D Printing a Clinically Available Solution From Plaster‐Based Positives in Superficial Radiation Therapy

open access: yesJournal of Medical Radiation Sciences, EarlyView.
This study compares two techniques for creating lead shielding masks to replace the current process for superficial/orthovoltage facial radiotherapy: Plaster Cast Positive Mould (PCPM), CT Scanned 3D Print (CT3DP), and Optical Scan 3D Print (OS3DP). CT3DP was found to be more accurate and preferred over OS3DP.

Utilisation of Objective and Subjective Image Quality Metrics to Guide Optimal Contrast Volumes for Abdominal CT

open access: yesJournal of Medical Radiation Sciences, EarlyView.
Determining the appropriate volume of iodinated contrast media (ICM) for portal venous phase abdominal CT is challenging. Objective image quality assessment demonstrates weight‐based volume dosing reduces the dependence of enhancement on patient size, compared to fixed volume.

Patient Centring in CT: An International Survey of Clinical Practice and Future Directions

open access: yesJournal of Medical Radiation Sciences, EarlyView.
An international survey of 321 radiographers from 43 countries found vertical mis‐centring below the CT isocentre is the most frequent positioning error. Only 34% had access to automated centring systems and 17% used them consistently. Substantial knowledge gaps exist regarding radiation dose and CT number variability, highlighting the need for ...

Pleural lipomatosis: A new pose of occult pleura effusion

open access: yesThe Egyptian Journal of Bronchology, 2016
Intrathoracic benign neoplasm can develop from any tissue; inside the thoracic cavity, however, infrequently, pleural lipomas can be detected, attributable to unusual adipose tissue in the pleural and subpleural layer.

Severe malnutrition and persistent myopenia despite weight recovery in newly diagnosed stricturing Crohn's disease: A case report

open access: yesNutrition in Clinical Practice, EarlyView.
Abstract Protein‐energy malnutrition is a common complication in Crohn's disease (CD). In addition to weight loss, patients may develop significant alterations in body composition, including skeletal muscle depletion, which can negatively affect clinical outcomes and quality of life.

Can the Hounsfield unit predict the success of medically expulsive therapy

open access: yesCanadian Urological Association Journal, 2013
Background: We investigate the predictability of medical expulsive therapy (MET) success with alpha blockers based on Hounsfield unit (HU) values and Hounsfield density (HD) values measured by computed tomography (CT) for distal ureteral stones.Methods: Between July 2011 and May 2012, 44 patients (19 female and 25 male) with 5- to 10-mm stones in the ...

Skeletal Muscle Mass Improvement and Survival After TIPS in Patients With Cirrhosis and Low Skeletal Muscle Index

open access: yesPortal Hypertension &Cirrhosis, EarlyView.
Sarcopenia is common in patients with cirrhosis and contributes to poor prognosis. This study investigated whether transjugular intrahepatic portosystemic shunt (TIPS) is associated with improvement in skeletal muscle mass and whether such improvement translates into better transplant‐free survival in patients with cirrhosis and low skeletal muscle ...
