We present a case of ruptured aneurysm in which extravasation of contrast medium was suspected during cerebral angiography and confirmed by computed tomography. In cases of ruptured aneurysm, post-angiographic computed tomography before operation (measurement of the Hounsfield unit numbers and grading by them) is necessary for establishing the diagnosis of extravasation of contrast medium and for grasping its degree and extent.

In the context of molecular imaging, the present work explores an innovative platform made of lipid-coated nanocrystals as contrast-enhanced agent for both ultrasound imaging and sonoluminescence. At first, the dynamics of gas bubbles generation and cavitation under insonation with either pristine or lipid-coated nanocrystals (ZnO-Lip) are described, and the differences between the two colloidal systems are highlighted. These ZnO-Lip show an unprecedented ability to assist cavitation, which is reflected in enhanced sonoluminescent light emission with respect to the pristine nanocrystals or the pure water.

Spontaneous ureteral rupture is a rare cause of acute abdominal pain, particularly unusual during pregnancy or the post-partum period. While pregnancy-related changes like ureteral compression and dilation may play a role, no definitive mechanisms have been established. Clinicians should suspect ureteric injury in post-partum patients with free pelvic fluid.

Objectives: To evaluate success, complications and efficacy for endovascular management for carotid blowout syndrome.
Methods: Images were evaluated for contrast extravasation, vessel wall irregularity, pseudoaneurysm/aneurysm formation. Hemostatic results in the immediate postprocedural period and procedure related infarcts were assessed.

A 10-year-old neutered male Labrador mix dog presented with a few-day history of stranguria and dysuria. Results of physical examination, laboratory findings, and imaging were consistent with a uroperitoneum and prostatomegaly. Ultrasound showed an enlarged, heterogeneous, and lobular prostate with mineralization, and fluoroscopy showed extravasation of contrast from the prostatic urethra through the prostatic parenchyma into the abdomen.

Objectives: The objective of this study is to evaluate the incidence and volume of contrast medium extrusion when activated with a laser and to compare these outcomes with those of other irrigation techniques.
Materials And Methods: Sixteen cadaver mandibles containing 116 single-rooted teeth were prepared using conventional rotary instrumentation. The teeth were randomly assigned to four irrigation groups: side-vented needle, sonic irrigation, laser activation at the orifice, and laser activation at the middle third of the canal.
