cross sectional male pelvis, scrotal & penile sonography
the part of the prostate that is in contact with the bladder is the
base
the anterior fibromuscular region or stroma
is anterior to most of the zonal anatomy
Denonvillier's fascia
lies between the prostate and the rectum
what is the echogenicity of the septum penis
low level echoes
Normal intratesticular arterial flow should exhibit
low resistance waveform
echogenicity of the epididymis
medium level echoes
what is the echogenicity of the corpora carvenosa
medium level echoes
the temperature of the testes is regulated by the
pampiniform plexus
the largest portion of the glandular prostate is the
peripheral zone
the epididymal head is connected to which portion of the testis
superior
the peripheral zone compromises what percentage of the glandular prostate
70%
testicular parenchyma on ultrasound is
heterogenous
echogenicity of the cavernosal arterial walls
high echogenicity
echogenicity of tunica albuginea
high echogenicity
excess fluid between the two layers of the tunica vaginalis is termed
hydrocele
on a sonogram of the prostate and seminal vesicles, the prostate normally appears
hyperechoic to the seminal vesicles
the normal AP diameter of the epididymal head is
10 to 12 mm
Semen is composed of
60% alkaline fructose, 13% to 33% alkaline fluid, and sperm
About 60% of semen is composed of
alkaline fluid rich in fructose, produced by the seminal vesicles.
When zones are compared on ultrasound, the peripheral zone may appear more echogenic than which structure(s)?
all of these
the main arterial blood supply of the penis includes the
deep artery of the penis, bulbourethral artery, and dorsal artery
the periurethral tissues can easily be differentiated from the anterior fibromuscular stroma
false
the prostate atrophies due to benign changes and infection
false
the transabdominal approach is superior for scanning the seminal vesicles and prostate compared to the transrectal approach
false
which statement is incorrect about the seminal vesicles
they are posterior to the urinary bladder and inferior to the prostate
normal serum prostatic specific antigen is less than 4
true
Convoluted seminiferous tubules connect to straight tubules, which empty into the
tunica albuginea
the penis is composed of
two corpora cavernosa dorsolaterally and the corpus spongiosum midventrally.
the area close to the center of the prostate is called the
verumontanum
When imaging or describing the glandular prostate, the best technique to describe the prostate is to use
zones
