Ultrasound of the shoulder

Jun 19, 2024 | radiopaedia.org | Frank Gaillard |Sonam Vadera

Ultrasound of the shoulder is a fast, relatively cheap, and dynamic way to examine the rotator cuff and is particularly useful in diagnosing:shoulder impingementshoulder instabilityrotator cuff disordersThe examination requires attention to technique and appropriate patient positioning. A high-frequency (7-12 MHz) probe is required to give sufficient anatomical resolution, and the examination can be performed from either in front or behind.
Spatial pulse length (ultrasound)

Jun 3, 2024 | radiopaedia.org | Sonam Vadera |Lachlan McKay

Spatial pulse length (SPL) in ultrasound imaging describes the length of time that an ultrasound pulse occupies in space. Mathematically, it is the product of the number of cycles in a pulse and the wavelength. A shorter SPL results in higher axial resolution. The minimum distance between two tissues that can be resolved in the axial dimension is equal to 1/2 * SPL 2. To improve axial resolution, SPL can be reduced by heavier damping or use of a higher frequency transducer 1.
Wearable biosensors

May 6, 2024 | radiopaedia.org | Sonam Vadera |Arlene Campos

Wearable biosensors are portable electronic devices that enable real-time monitoring and feedback to the user on various biological and physiological indicators. It has been suggested that they could revolutionise personalised healthcare and home management of patients by enabling continuous monitoring of vital signs 1,2. Methods by which wearable biosensors can integrate sensors into the human body include smart watches, implants, clothing, tattoos, patches or rings.

Tibial plateau fracture

Apr 18, 2024 | radiopaedia.org | Sonam Vadera

Tibial plateau fractures were originally termed a bumper fracture or fender fracture but only 25% of tibial plateau fractures result from impact with automobile bumpers. The most common mechanism of injury involves axial loading, e.g. fall from a significant height. In younger patients, the most common pattern of fracture is splitting, while in older, more osteoporotic patients, depression fractures typically are sustained.
Knee menisci | Radiology Reference Article | Radiopaedia.org

Apr 10, 2024 | radiopaedia.org | Henry Knipe |Sonam Vadera

The knee menisci are fibrocartilaginous structures that sit within the knee joint, deepening the tibiofemoral articulation. Their main role is shock absorption, improve stability of the knee joint, and load transmission. They also play an important role in synovial fluid dynamic circulation and also considered by some to be involved in proprioception.

Mitrofanoff procedure

Feb 23, 2024 | radiopaedia.org | Sonam Vadera |Yuranga Weerakkody

The Mitrofanoff procedure, also known as appendicovesicostomy, is a surgical procedure where a conduit is created using the appendix to form a connection between the urinary bladder and skin surface. Intermittent catheterization is performed through the surgically constructed conduit, thus providing an alternative to urethral intermittent catheterization in patients who are unable to tolerate the latter 1,2.
