Ultrasound measurements of pathological and physiological skin thickness: a scoping review protocol

Abstract

IntroductionUltrasound is a quick, safe, and non-invasive imaging method that can be used to measure skin thickness in pathological cutaneous conditions in clinical and research settings. Despite widespread use, there exists a lack of standardisation and reporting of ultrasound skin thickness measurement methods, which makes between-studies comparisons difficult. To address this, we present a scoping review protocol, which aims to determine what is and is not known about the measurement of skin and scar thickness using ultrasound in people with traumatic scars.Methods and analysisThe Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews guidelines and Joanna Briggs Institute scoping review methodology will be used to guide this review. Electronic database searching will be conducted in Ovid MEDLINE, Embase, Cumulative Index of Nursing and Allied Health Literature and Web of Science. No date limit will be imposed on the database searches. Records will be supplemented with searches of reference lists of included studies and grey literature in OpenGrey and Google Advanced. Screening will be conducted by two independent reviewers, and studies where ultrasound is used to measure skin and scar thickness in people with traumatic scars will be included. Data extraction will include ultrasound methods (eg, transducer orientation), psychometric properties (eg, reliability, measurement error), health service and implementation outcomes (eg, feasibility, acceptability) and factors influencing ultrasound measurement of skin thickness (eg, body location, age).Ethics and disseminationEthical approval is not required for this investigation, as published literature will form the basis of the review. The review will be published in a peer-reviewed scientific journal and is expected to result in the development of the first evidence-based and consensus-based methodological guideline for skin thickness measurement by ultrasound.

Ultrasound measurement of traumatic scar and skin thickness: a scoping review of evidence across the translational pipeline of research-to-practice

“…The protocol for this review has been published a priori 37. This scoping review was conducted and is reported according to the framework by Arksey and O’Malley 38.…”

Skin Cancer Pathobiology at a Glance: A Focus on Imaging Techniques and Their Potential for Improved Diagnosis and Surveillance in Clinical Cohorts

“…A lot of devices may incorporate color Doppler analysis for the characterization of blood flow and vessel morphology within the suspected skin lesions [ 112 ]. Regarding the amplitude mode (A-mode), the computer generates a one-dimensional line graph that can be used to interpret echogenicity at various distances from the probe [ 112 , 113 ]. The so-called echogenicity represents the internal echo pattern—or the ability of a structure to reflect sound waves relative to its surrounding tissue [ 114 ].…”

The growing importance of high-efficiency ultrasound in diagnosis and management of dermatological diseases

“…[5] Po raz pierwszy USG w dermatologii zastosowali Alexander i Miller w 1979 roku do pomiaru grubości ludzkiej skóry -zastosowane wówczas częstotliwości (15MHz) nie pozwalały na rozróżnienie poszczególnych jej warstw, ale dało to początek dalszym badaniom w tym obszarze. [3,6] Jednakże, dynamiczny rozwój ultrasonografii skóry rozpoczął się na przełomie XX i XXI wieku, co było zasługą postępu w nowych technologiach komputerowych. Przełomem było wprowadzenie ultrasonografii wysokich częstotliwości.…”
