“…So far small sized handheld devices have been mainly studied in cardiology (echocardiography) [4,6,33,35,68], vascular indications mainly focusing on abdominal aorta aneurysm [15,18,23,37,[61][62][63] and in the setting of Focused Assessment with Sonography for Trauma (FAST) [4,17,23,35,[69][70][71]. Studies on the use of abdominal diseases are sparse [2,22,[72][73][74] and except one [2] mainly focus on case reports [72] and acute cholecystitis patients [74].…”

Background and aims:The introduction of a new type of small handheld ultrasound device brings greater portability and affordability in a different setting. The basic ultrasound approach with these handheld devices has been defined by European Federation of Societies of Ultrasound in Medicine and Biology (EFSUMB) as "EchoScopy". The current study aimed to assess the image quality, indications and limitations of a portable pocket "EchoScopy" performed first compared with a high-end ultrasound system (second) in abdominal diseases.Material and methods: Three hundred consecutive patients (158 males and 142 females, age 55±19 [18-96]) years) were included. The ultrasound examinations were performed firstly by an EchoScope (Vscan™ Dual Probe) and secondly with a high-end ultrasound system (HEUS, GE Logiq E9). Compared with the always excellent image quality using HEUS, the image quality of the EchoScope was graded as good, sufficient or non-sufficient. Results: Out of all 300 patients, 221 had focal lesions, 31 patients were found with diffuse pathological findings, 20 with ascites, 25 after liver puncture and 45 without any pathological findings. The image quality of the pocket device was considered as being good or sufficient to delineate the pathology in 265/300 (88%). The detection rate of the EchoScope for abdominal focal lesion was 172/221 (78%). The higher frequency of the Dual Probe was helpful in 35/300 (12%). Conclusions: EchoScopy has proven to display sufficient image quality to answer specific questions, e.g., detection of ascites, splenomegaly, bile duct enlargement, hydronephrosis and other pathological findings which can be judged by "yes/no".

“…Therefore, only well-trained echocardiographists should perform conventional US for the detection of AAA. Hence Vidakovic et al 4 proposed to use the automatic BVI 6400 system for AAA screening because of (i) potential widespread availability, (ii) low costs (10.000 E) compared with expensive conventional US equipment, and (iii) steep learning curve compared with more intensive training required for conventional US. They concluded that the BVI 6400 is simpler for use, requires a less intensive training period and therefore can be used by a nurse or a technician.…”

“…16 In 2003, for instance, portable cardiac US (or echo-stethoscope) broadened the application of echocardiography to the patient's bedside. 17 The use of portable US for AAA detection was first described by Vidakovic et al, 4 using the automatic BVI 6400 system.…”

“…A simple screening device, which is less expensive and offers the possibility for use outside the hospital, might be the key solution for widespread AAA screening. In 2006, a pilot study conducted by Vidakovic et al 4 demonstrated the diagnostic potential of an automatic bladder volume scanner (BVI 6400, Verathon Medical, Bothell, USA) to detect AAA. The current study evaluated the diagnostic accuracy of a new portable ultrasound scanner [Aortascan BVI 9600 (BVI 9600), Verathon Medical] developed for automatic AAA detection.…”

Aims Abdominal aortic aneurysms (AAA) are often diagnosed at time of (impending) rupture leading to a dramatic increase of morbidity and mortality. A simple screening device might be the key solution for widespread AAA screening. This study evaluated the diagnostic accuracy of a new portable ultrasound scanner (Aortascan BVI 9600) developed for automatic AAA detection. Methods and results A total of 150 patients with presumed aneurysmatic peripheral atherosclerotic disease were included in the study. Patients were first scanned with conventional ultrasound (US), serving as reference technique. An infra-renal abdominal aorta diameter of 30 mm was defined as an AAA. Hereafter, the aorta was scanned using the Aortascan BVI 9600. Statistical analyses were performed using SPSS version 15.0 statistical software. Abdominal aortic aneurysms were detected with conventional US in 78 (52%) patients, compared with 74 (49%) AAA's detected with Aortascan BVI 9600. The Aortascan BVI 9600 demonstrated a sensitivity, specificity, positive and negative predictive value of 90, 94, 95, and 89%, respectively, in the detection of AAA's. Conclusion The Aortascan BVI 9600 automatically detects the aortic diameter with a 90% sensitivity without the need for a trained operator. Because of these unique capabilities, it can be used for AAA screening outside the hospital.
