1.
(E) |
以下何者為非? |
A | 正子電腦斷層掃描檢查 (PET)
乃藉著在人體注射帶有正電子的放射線同位素,透過掃描去偵察細胞的功能或新陳代謝速度。近年來,利用FDG(18-fluoro-2-deoxyglucose,氟-18去氧葡萄糖)所做的正子造影,已漸漸成為臨床上一項重要的癌症診斷工具。 |
B | PET是全身性的掃描,可以偵測全身性的病灶。 |
C | FDG
PET能夠發現的癌症以肺癌、甲狀腺癌、大腸癌居多。 |
D | PET的檢查可能可以在徵狀出現前或是腫瘤指數正常時,發現是否有癌症、復發或轉移,臨床上是很好的診斷跟追蹤工具。 |
E | FDG PET的代謝增加處一定是癌症。 |
2.
(A) |
以下何者為非? |
A | 各種腫瘤都會攝取FDG。 |
B | 很小的腫瘤
(尤其是0.5公分以下),因為PET解析力的問題,仍有其侷限。 |
C | FDG經由腎及泌尿系排泄,對於腎臟、膀胱及附近腫瘤需小心鑑別;同時在掃描前需要儘可能的排空膀胱,以減少膀胱內尿液放射性造成困擾。 |
D | 空腹血糖過高時可能會影響FDG
PET的影像及判讀。 |
E | FDG PET在區分腦癌、正常腦或腦腫瘍上有鑑別困難之處。 |
3.
(D) |
Which of the following
test results would be highly useful in EXCLUDING the diagnosis of
PULMONARY EMBOLISM (PE)? |
A | Normal PaO2 by ABG |
B | Absence of right heart strain
on ECG |
C | Intermediate probability of
V/Q scan |
D | Normal plasma level of
D-Dimer |
E | Normal CT scan of the chest |
4.
(D) |
Following
hypercoagulable condition is possible underlying cause of patients
who have PE, which is wrong? |
A | Protein C or S deficiency |
B | Bed ridden |
C | Oral contraceptive |
D | Sarcoma |
E | Pregnancy |
5.
(D) |
Which of the following
statement of PE is wrong? (A) (B) (C) (D) (E) |
A | The response to thrombolytic
therapy is better in acute PE, and could be considered in patients
with progressively respiratory distress |
B | The extent of vascular
obstruction is a major determinant of pulmonary hypertension, and
more than 40% of obstruction is noted in the most patients who were
diagnosed to have PE |
C | Without intervention, the rate
of survival is low and proportional to the degree of pulmonary
hypertension at time of diagnosis |
D | The ventilation scan is still
indicated even in the completely normal perfusion scan |
E | Evaluation of underlying
disease is important when PE is diagnosed |
6.
(B) |
Which of the following
statements of PE is wrong? |
A | Right heart cath should
be considered in any patient with unexplained dyspnea and segmental
or larger defects on ventilation-perfusion scan, especially in
patients with RV dysfunction |
B | Pulmonary thromboendarectomy
is considered in all patients who were diagnosed PE |
C | The location and extent of the
proximal thrombolic obstruction are the most critical determinants
of operability |
D | Lifelong anticoagulation
therapy is usually recommended after thromboendarectomy |
E | Residual pulmonary
hypertension and RV dysfunction might be noted after
thromboendarectomy |
