2025
Voiding Cystourethrography (VCUG) and Cystography are specialized radiographic procedures used to examine the structure and function of the bladder and urethra.Voiding Cystourethrography (VCUG)A Voiding Cystourethrogram (VCUG) is a diagnostic imaging procedure that assesses the anatomy and function of the lower urinary tract. It focuses on the bladder, bladder neck, and urethra, helping detect abnormalities such as vesicoureteral reflux (VUR)—the backward or reverse flow of urine into the...

Total Voids in Concrete

Total voids in concrete encompass gel water volume, capillary pores, and entrapped air. Gel water (retained within the cement hydration products) and physically entrapped or adsorbed water are significant for the hydration process. For complete hydration, it's estimated that the space needed for the products of a cubic centimeter of cement doubles. Capillary pores constitute the unoccupied space within the hydrated cement paste, with their size largely influenced by the water-to-cement ratio...

Accurate financial reporting relies on more than just recording transactions; it requires systematically updating and organizing data across various accounting records. One critical step in this process is posting to the ledger, which bridges daily transaction entries with meaningful financial summaries.Posting involves transferring each journal entry to the appropriate ledger accounts, ensuring all changes in financial position are categorized by type—assets, liabilities, equity, income, or...

Source: Faisal Alamgir, School of Materials Science and Engineering, Georgia Institute of Technology, Atlanta, GA The imaging of microscopic structures of solid materials, and the analysis of the structural components imaged, is known as materialography. Often, we would like to quantify the internal three-dimensional microstructure of a material using only the structural features evidenced by an exposed two-dimensional surface. While X-ray based tomographical methods can reveal buried...
FAQs
Bladder ultrasound estimates post-void residual volume by using measurements of the fluid-filled bladder after urination. The resulting estimate provides an objective indication of how much urine remains rather than relying only on symptoms. Clinicians can use this measurement to assess emptying effectiveness and decide whether additional evaluation of lower urinary tract function is warranted.
The timing of the scan is central to interpretation: imaging is obtained immediately after the patient voids, so the measurement reflects bladder contents in the post-void state. This supports evaluation of incomplete emptying and urinary retention. Repeating the assessment over time can also show whether bladder emptying changes with symptoms or treatment.
An increased residual volume can support concern about urinary retention or incomplete emptying, while the broader clinical pattern helps determine possible relevance to bladder outlet obstruction or neurogenic bladder. The measurement serves as an assessment finding, not a complete explanation by itself. Clinicians interpret it alongside the patient’s presentation and other evaluation.
Unlike a catheter-based assessment, post-voiding imaging uses bladder ultrasound to estimate residual volume without requiring catheterization. That distinction makes the assessment rapid and noninvasive, which is useful when clinicians need repeated measurements. It allows bladder emptying to be followed without introducing a catheter as part of the measurement process.
During a typical assessment, the patient urinates first, and bladder ultrasound is then obtained immediately afterward. The scanner measures the fluid-filled bladder and estimates the volume remaining. This workflow focuses on the post-void measurement, allowing clinicians to assess how effectively the bladder emptied during a quick, noninvasive clinical encounter.
Clinicians may use serial post-voiding imaging to monitor urinary symptoms, response to treatment, and changes in bladder function over time. The test can contribute to evaluation when incomplete emptying, retention, bladder outlet obstruction, or neurogenic bladder is being considered. Comparing measurements across assessments helps provide clinical context for changes in lower urinary tract function.
