MRI
the most commonly used noninvasive study to assess regional blood flow and tissue viability of the myocardium is
NM perfusion scan

US
which of the following i s/are a type(s) of aneurysm
all of the above -saccular -fusiform -weakness in the blood vessel wall

aneurysm
localized dilation of of an artery is an
aneurysm
a structure extending from the pulmonary artery to what vessel occurs in a pt with patent ductus arteriosus
aorta
The classic double barrel aorta is indicative of
aortic dissection
___ is a disorder that can be caused by sypilis, infective carditis, a dissection aneurysm or Marfan's syndrome
aortic insufficiency
free communication btw the atria is ___, which has a left-to-right shunting effect
atrial septal defect
the most common congenital cardiac lesion is
atrial septal defect
regurgitation indicates
backflow of blood
essential hypertension characterized by a gradual onset and a prolonged course is a
benign form
a bilateral symmetrical fan-shaped infiltration seen on a posteranterior chest radiograph is the characteristic ___ sign of ___
butterfly pulmonary edema
A constriction of the aorta causing reduced blood flow to the abdominal organs and the lower extremities is called ______________ of the aorta
coarctation
When the heart lacks the ability to adequately supply the body with blood, the patient has
congestive heart failure
the definitive procedure to determine the prescence and severity of coronary artery disease is
coronary arteriography
___ begins with an intimal tear in the aorta
dissection
For diagnosing DVT with a noninvasive approach, the modality with 95% accuracy is:
duplex color doppler US
if the first impulse in the conduction system of the heart fails to fire, what structure will generate rhythmic impulses at a slower than normal rate
ectopic pacemaker
to best demonstrate the location and extent of an aneurysm, the diagnosticians' choice in imaging is
either a or b -CTA -MRA
the string-of-beads pattern on a renal arteriogram suggests
fibomuscular dysplasia
the most common underlying disorder causing renovascular hypertension is
fibromusclar dysplasia
___ is most commonly seen in young women and appears radio graphically as a string-of-beads
fibrous dysplasia
the cardiothoracic (C/T) ratio is used to evaluate
heart size
The continued strain of what condition leads to dilation and enlargement of the left ventricle?
hypertensive heart disease
a result of long-standing hypertension is
hypertensive heart disease
Bacteria or fungi form vegetations on the heart valves
infective carditis
the development of nodules or vegetations on heart valves caused by deposits of bacteria or fungi is indicative of
infective carditis
To demonstrate venous patency in varicose veins, the procedure of choice is
lower leg venography
when coronary vasculatization is occluded, the area of the myocardium loses its blood supply, causing
myocardial infarction
DVT can be caused by
oral contraceptives
a saccular aneurysm is defined as an
outpouching only on one side of the artery
on echocardiography, a posterior sonolucent fluid collection surrounding the heart is suggestive of
pericardial effusion
fatty deposits in the artery cause
plaques
valve insufficiency occurs in pts with
poor cardiac output
The butterfly or bat's wing pattern, which is most prominent in the central portion of the lungs, is indicative of
pulmonary edema
___ refers to an abnormal accumulation of fluid in the extra vascular pulmonary tissue
pulmonary edema
cyanotic congenital heart disease consists of four abnormalities; high ventricular septal defect, overriding of the aortic orifice above the ventricular defect, right ventricular hypertrophy and
pulmonary stenosis
coarctation of the arorta is demonstrated radiographically as
rib notching and two bulges in the region of the aortic knob
a complication of infective carditis is
septic emboli
varicose veins usually involve the
superficial veins
an aortic dissection is a
tear in the intima
the classic coeur en sabot appearance, in which the heart resembles the curved-toe portion of the wooden shoe, appears in cases of
tetralogy of fallot
in hypertensive heart disease, the narrowing of the systemic circulation causes
the left ventricle to assume an increased workload
a hemorrhage into the mediastinum causes a mediastinal widening and a loss of a discrete aortic knob shadow in
traumatic aortic rupture
to identify a clot within an aneurysm, the modality of choice is
CTA
right-sided heart failure causes
a backflow of blood in the venous systemic circulation
