Abstract Aims. To evaluate the agreement between a visual and an automatic counting system of lung B-lines by ultrasound (US) as well as to test the inter- and intra-observer reliability of both systems in patients with lung diseases. Material and methods. We included four patients with different lung conditions. Four ultrasonographers expert in lung US blindly, independently and consecutively performed, in two rounds, a US B-mode assessment of 8 lung intercostal spaces of each patient. Each US assessment consisted of a visual and an automatic counting of B-lines. Results. Agreement between visual and automatic counting of B-lines was good to excellent [intraclass correlation coeffcient (ICC) 0.79-0.84, p<0.001]. Intra-observer reliability was good to excellent [ICC 0.62-0.99, p<0.001] except for one investigator in whom it was close to moderate for the automatic system [ICC 0.49, p<0.05]. Inter-observer reliability was excellent for both systems in both rounds [ICC 0.86-0.90, p<0.001]. Conclusions. US automatic counting was consistent with US visual counting of lung B-lines, as performed by experts in the feld. Both systems showed a high intra- and interobserver reliability.

“Ultrasound is a volume created by many frames, so all the data exist but cannot be seen. By taking apart the video and building it again we can navigate inside and see everything that’s going on,” explains Adi Baruch, cofounder and CEO of iNNOGING Medical. “Our technology quite simply converts the video clip into a 3D model.” The doctor maneuvers through this 3D model with iNNOGING’s Probe & Pad hardware attached to any computer. The probe is identical to the transducer used in a live ultrasound exam, while the pad simulates the patient’s body. There’s no special training needed for any doctor who already knows how to perform an ultrasound. “It’s like the patient is sitting right there getting a real-time exam,”

ABSTRACT Hydrocolpos is commonly due to obstructive causes such as imperforate hymen and vaginal septum. Transient hydrocolpos or non-obstructive hydrocolpos is an under-recognized entity due to a phenomenon called "vesicovaginal reflux" (VVR). It is commonly seen during voiding cystourethrography although it is not a familiar entity for radiologists. Failure to recognize VVR often leads to unnecessary higher imaging modalities. We report a case of young married woman who presented with daytime urinary continence and found to have transient hydrocolpos due to VVR.

Ultrasound has been shown to be an effective supplemental screening tool, detecting cancers that are mammographically occult due to dense breast tissue. Although specificity was found to be lower in the intervention group, sensitivity was found to be significantly higher. Further, cancers detected by screening ultrasound have been shown to be smaller and node-negative, indicating early stage breast cancer.[By screening with ultrasound and finding cancer at an earlier stage, it is possible to avoid the financial burden of later treatments in addition to the mental and physical burden women are faced with.
