Pelvimetry is the measurement of the female pelvis. [1] It can theoretically identify cephalo-pelvic disproportion, which is when the capacity of the pelvis is inadequate to allow the fetus to negotiate the birth canal. However, clinical evidence indicate that all pregnant women should be allowed a trial of labor regardless of pelvimetry results.
Imaging includes transvaginal and abdominal ultrasound, CT scan, and MRI. [2] Pathologic assessment may include SEE-FIM Protocol. [1] A pelvic mass may be detected on a routine gynecologic examination. [2] It may be found at an early stage when removing the tubes and ovaries as a preventive measure. [1]
The urogenital diaphragm, or perineal membrane, is present over the anterior pelvic outlet below the pelvic diaphragm. [5] The exact structure description is controversial. Despite the controversy, MRI imaging studies support the existence of the structure. [3] [6] Superficial and inferior muscles of the perineum (urogenital diaphragm ...
The same human pelvis, front imaged by X-ray (top), magnetic resonance imaging (middle), and 3-dimensional computed tomography (bottom). The pelvis (pl.: pelves or pelvises) is the lower part of an anatomical trunk, [1] between the abdomen and the thighs (sometimes also called pelvic region), together with its embedded skeleton [2] (sometimes also called bony pelvis or pelvic skeleton).
The pudendal nerve is the main nerve of the perineum. [1]: 274 It is a mixed (motor and sensory) nerve and also conveys sympathetic autonomic fibers.It carries sensation from the external genitalia of both sexes and the skin around the anus and perineum, as well as the motor supply to various pelvic muscles, including the male or female external urethral sphincter and the external anal sphincter.
The rectouterine (or recto-uterine) pouch is also called the rectouterine excavation, uterorectal pouch, rectovaginal pouch, pouch of Douglas (after anatomist James Douglas, 1675–1742), Douglas pouch, [6] Douglas cavity, [6] Douglas space, [6] Douglas cul-de-sac, [6] Ehrhardt–Cole recess, Ehrhardt–Cole cul-de-sac, cavum Douglasi, or excavatio rectouterina.
Gynecologic ultrasonography or gynecologic sonography refers to the application of medical ultrasonography to the female pelvic organs (specifically the uterus, the ovaries, and the fallopian tubes) as well as the bladder, the adnexa, and the recto-uterine pouch. The procedure may lead to other medically relevant findings in the pelvis.This ...
Abdominal imaging is associated with many potential uses for the different phases of contrast CT.The majority of abdominal and pelvic CT's can be performed using a single-phase, but the evaluation of some tumor types (hepatic/pancreatic/renal), the urinary collecting system, and trauma patients among others, may be best performed with multiple phases.
