- Abstract
- Scrotal imaging with technetium-99m
sodium pertechnetate consists of a
radionuclide angiogram and static
scrotal scans. Utilization of this
study in patients presenting with an
acute scrotum can dramatically reduce
the number of surgical explorations
for acute epididymitis. It can also
aid in other aspects of differential
diagnosis in patients presenting with
either an acutely enlarged and/or
painful scrotum or a scrotal mass.
Ambiguities in previous descriptions
of perfusion through the spermatic and
extraspermatic cord vessels are
described and distinguished from
scrotal perfusion. The clinical and
scintigraphic spectrum of testicular
torsion, including spontaneous
detorsion, early acute testicular
torsion, midphase testicular torsion,
and late phase or "missed
testicular torsion," is discussed
and illustrated. The variety of
patterns seen in acute epididymitis,
including lateral and medial
epididymal location, and focal
epididymitis are described, as is the
appearance of hydrocele as both a
primary and secondary entity. The
relationship of scrotal imaging to the
overall clinical presentation and
evaluation of these patients is
emphasized in testicular torsion,
torsion of the testicular appendages,
epididymitis, abscess, trauma, tumor,
spermatocele, and varicocele. The
techniques, clinical utility, and
relationship to radionuclide imaging
of Doppler ultrasound and gray scale
ultrasound scanning are reviewed.
Doppler ultrasound results in many
false negative studies in testicular
torsion. Gray scale ultrasound is
useful in clarifying the nature of
scrotal masses.

- Abstract
- BACKGROUND: Coronary angiography is
still the routine screening method for
cardiac allograft vasculopathy in most
transplant centers. This study was
designed to analyze functional and
morphologic changes in heart
transplant recipients with normal
angiographic findings. METHODS:
Dobutamine stress echocardiography and
intracoronary ultrasound were obtained
in 56 patients with a normal coronary
angiogram 41+/-31 months after heart
transplantation. Intracoronary Doppler
flow velocity measurements before and
after intracoronary adenosine
administration were performed in 34 of
56 patients. Any regional wall motion
abnormalities detected by stress
echocardiography were regarded as
abnormal. By quantitative
intracoronary ultrasound analysis
using a 6-grade scale, a mean grade of
all coronary segments >3.0 was
defined as significant intimal
hyperplasia. RESULTS: Only 17 patients
(30%) showed both a normal dobutamine
stress echocardiogram and absence of
significant intimal hyperplasia by
intravascularultrasound. Abnormal
findings were observed in 39 patients
(70%): both by dobutamine stress
echocardiography and intravascular
ultrasound in 22 patients, by
intravascular ultrasound alone in 11
patients, and by dobutamine stress
echocardiography alone in 6 patients.
Coronary flow velocity reserve did not
discriminate between patients with
normal or abnormal intravascular
ultrasound or dobutamine stress
echocardiographic findings.
Conclusions: Only a minority of heart
transplant patients with a normal
coronary angiogram is free of
pathological changes, when assessed by
intravascular ultrasound and
dobutamine stress echocardiography.
Coronary flow velocity reserve does
not seem useful to further
characterize these patients.

- Abstract
- A case of post-traumatic aneurysm of
the profunda femoris artery following
self-administration of an
intramuscular injection is reported.
The diagnosis was made prior to
contrast arteriography on the basis of
a radionuclide angiogram performed as
part of a bone scan. Additional
confirmation was obtained by
ultrasound examination.

- Abstract
- A 15-yr-old boy, who had had surgery
for a choledochal cyst in infancy, was
worked up for recurrent right upper
quandrant pair. Intravenous
cholangiogram and ultrasound
demonstrated a choledochal cyst with
stones. Angiogram showed only a
distorted branch of the
gastro-duodenal artery. These findings
were confirmed at surgery.

- Abstract
- The correct diagnosis was
established by angiography in 16 of 21
patients with pancreatic pseudocyst.
The characteristic angiographic
abnormalities are arcuate stretching
of intrapancreatic arteries combined
with a filling defect in the
parenchymal phase of the angiogram. In
the five false negative patients, the
diagnosis was not made either because
of the small size of the pseudocyst or
a primary extrapancreatic location of
the lesion. Because of this high false
negative rate and the accuracy of
B-mode ultrasonic scanning in
abdominal cystic lesions, ultrasound
should be the primary diagnostic
modality in patients with suspected
pancreatic pseudocysts.

- Abstract
- PURPOSE: To present the
ultrasonographic findings of the
cervico-cerebral arteries in
patients with Takayasu arteritis.
MATERIALS AND METHODS: We used
duplex ultrasound to study the
arteries in the neck including the
common carotid artery (CCA),
internal carotid artery (ICA),
external carotid artery (ECA) and
the vertebral arteries. For the
intracranial arteries, transcranial
Doppler ultrasound was used to study
the blood flow velocities and
directions in the middle cerebral
artery (MCA), anterior cerebral
artery (ACA), posterior cerebral
artery (PCA), ophthalmic artery,
basilar and vertebral arteries. The
ultrasonographic findings were
compared with magnetic resonance
angiography (MRA) and standard
angiography. RESULTS: Four patients
with the diagnosis of Takayasu
arteritis were studied. One patient
presented with ischemic optic
neuropathy and was found to have
absent radial pulse. Two patients
presented with severe hypertension
in young age. The other patient had
accidental findings of unmeasurable
blood pressure in both arms. One
patient had abnormal carotid duplex
ultrasound. He was found to have an
occlusion of the right ICA.
Thickening of the wall of the left
ICA was also noted. Reduction of
flow velocity in the MCA was
demonstrated on TCD. There was
evidence of collateral circulation
from the contralateral carotid
artery demonstrated by reversal of
flow in the ipsilateral A1 segment
of the ACA. MRA and angiography
confirmed the ultrasound findings.
Three patients had normal carotid
duplex ultrasound
