Abdominal and Pelvic Radiology Indian Medical PG Practice Questions and MCQs
Practice Indian Medical PG questions for Abdominal and Pelvic Radiology. These multiple choice questions (MCQs) cover important concepts and help you prepare for your exams.
Abdominal and Pelvic Radiology Indian Medical PG Question 1: A 30 year old female comes with hypovolemic shock after blunt trauma of the abdomen. An emergency USG of abdomen shows splenic tear. Which of the following is to be done -
- A. Monitor patient to assess for progression
- B. CECT of the abdomen
- C. Immediate surgery (Correct Answer)
- D. Diagnostic lavage of peritoneal cavity before proceeding
Abdominal and Pelvic Radiology Explanation: ***Immediate surgery***
- A patient in **hypovolemic shock** after a **blunt abdominal trauma** with a confirmed **splenic tear** on ultrasound (FAST scan) indicates active hemorrhage and hemodynamic instability.
- In such a critical state, **immediate surgical intervention** (laparotomy) is necessary to control bleeding and stabilize the patient's condition, as non-operative management is contraindicated.
*Monitor patient to assess for progression*
- This approach is suitable for **hemodynamically stable** patients with splenic injuries, where observation and serial examinations can be considered.
- Given the patient's **hypovolemic shock**, monitoring alone risks critical delays in hemorrhage control, leading to further decompensation.
*CECT of the abdomen*
- An abdominal **CT scan with contrast** (CECT) is the gold standard for detailed assessment of abdominal injuries but requires the patient to be **hemodynamically stable**.
- Performing a CECT on a patient in **hypovolemic shock** would delay life-saving intervention and is not appropriate for this unstable condition.
*Diagnostic lavage of peritoneal cavity before proceeding*
- **Diagnostic peritoneal lavage (DPL)** is an older, invasive diagnostic test used to detect intra-abdominal bleeding, but it has largely been replaced by **FAST scans** and **CT scans**.
- In this case, the **FAST scan already confirms a splenic tear**, and the patient's **hypovolemic shock** necessitates immediate definitive treatment rather than an additional diagnostic step.
Abdominal and Pelvic Radiology Indian Medical PG Question 2: Which of the following statements regarding a patient of liver trauma are correct?
1. Liver is the most common organ injured following abdominal trauma.
2. Surgical exploration (laparotomy) is required in haemodynamically unstable patients and patients with free intraperitoneal fluid on FAST.
3. Contrast enhanced CT abdomen should be done in haemodynamically stable patients.
4. Blunt injuries have a higher mortality as compared to penetrating injuries.
- A. 1. Liver is the most common organ injured following abdominal trauma.
- B. 2. Surgical exploration (laparotomy) is required in haemodynamically unstable patients and patients with free intraperitoneal fluid on FAST.
- C. 4. Blunt injuries have a higher mortality as compared to penetrating injuries.
- D. 3. Contrast enhanced CT abdomen should be done in haemodynamically stable patients. (Correct Answer)
Abdominal and Pelvic Radiology Explanation: ***3. Contrast enhanced CT abdomen should be done in haemodynamically stable patients.***
- A **contrast-enhanced CT abdomen** is the diagnostic study of choice for **hemodynamically stable patients** with suspected liver trauma, as it accurately quantifies injury and guides management.
- It helps in grading the liver injury, identifying active extravasation, and detecting associated injuries, thus determining the need for operative versus non-operative management.
*1. Liver is the most common organ injured following abdominal trauma.*
- While the liver is frequently injured in abdominal trauma, the **spleen** is actually the most commonly injured solid organ in cases of **blunt abdominal trauma**.
- The liver is the second most commonly injured solid organ, but its large size and fragile nature make it highly susceptible to injury.
*2. Surgical exploration (laparotomy) is required in haemodynamically unstable patients and patients with free intraperitoneal fluid on FAST.*
- **Hemodynamically unstable patients** with suspected abdominal trauma often require **surgical exploration (laparotomy)**, but the presence of **free intraperitoneal fluid on FAST** alone does not automatically necessitate laparotomy in stable patients.
- Free fluid on FAST in a stable patient can represent blood or other fluid, and further imaging like CT is needed to assess the source and extent of injury before surgical intervention.
*4. Blunt injuries have a higher mortality as compared to penetrating injuries.*
- **Penetrating injuries** (e.g., stab wounds, gunshot wounds) generally have a **higher mortality rate** than blunt injuries due to the direct damage to vital structures and risk of massive hemorrhage and infection.
- While blunt injuries can be severe, they often lead to less direct and immediate damage to major vessels and organs compared to penetrating trauma.
Abdominal and Pelvic Radiology Indian Medical PG Question 3: The imaging modality primarily used in FAST (Focused Assessment with Sonography for Trauma) exam is:
- A. X-ray
- B. CT
- C. MRI
- D. USG (Correct Answer)
Abdominal and Pelvic Radiology Explanation: **USG**
- **Focused Assessment with Sonography for Trauma (FAST)** exam specifically uses **ultrasound (USG)** to rapidly detect free fluid (blood) in pericardial, perihepatic, perisplenic, and pelvic spaces.
- Its quick, non-invasive nature and portability make it ideal for **point-of-care assessment** in trauma settings.
*X-ray*
- While X-rays are useful in trauma for detecting **fractures** and some pneumothoraces, they are not the primary modality for detecting free fluid in the peritoneal or pericardial cavities during a FAST exam.
- X-rays do not provide real-time, dynamic imaging of soft tissues and fluid accumulation as effectively as ultrasound.
*CT*
- **Computed Tomography (CT)** is a highly detailed imaging modality used in trauma for comprehensive assessment of injuries to organs, bones, and vessels.
- However, it involves **radiation exposure**, takes longer to perform, and is typically reserved for hemodynamically stable patients after initial resuscitation and FAST exam.
*MRI*
- **Magnetic Resonance Imaging (MRI)** provides excellent soft tissue contrast, but its use in acute trauma is very limited due to its **long scan times**, high cost, and incompatibility with many metallic medical devices.
- MRI is not suitable for rapid assessment of free fluid in hemodynamically unstable trauma patients.
Abdominal and Pelvic Radiology Indian Medical PG Question 4: Patients who need surgery within 24 hours are categorized under which color category in a disaster management triage?
- A. Green
- B. Yellow (Correct Answer)
- C. Blue
- D. Black
Abdominal and Pelvic Radiology Explanation: ***Yellow***
- Patients in the **yellow category** are those who require **significant medical attention** and intervention, such as surgery, but whose condition is stable enough to withstand a delay of a few hours up to 24 hours without immediate threat to life or limb.
- This category indicates a **delayed but urgent need** for treatment, distinguishing them from immediate (red) or minor (green) cases.
*Blue*
- The color **blue** is generally **not a standard triage category** in most commonly used disaster protocols (e.g., START, JumpSTART).
- Triage systems typically use red, yellow, green, and black to prioritize patients based on immediate medical need and prognosis.
*Green*
- The **green category** is for patients with **minor injuries** who are considered "walking wounded" and can often wait for treatment for several hours, sometimes up to a few days.
- These individuals are **stable** and do not require immediate intervention to preserve life or limb.
*Black*
- The **black category** is reserved for individuals who are **deceased** or have injuries so severe that survival is unlikely given the available resources, often implying **palliative care** rather than active life-saving interventions in a mass casualty event.
- This category signifies that resources would be better allocated to patients with a higher chance of survival.
Abdominal and Pelvic Radiology Indian Medical PG Question 5: Which of the following is the correct management of abdominal compartment syndrome?
- A. Antihypertensives
- B. Urgent Fasciotomy
- C. Wait and monitor for 24 hours
- D. Urgent decompressive laparotomy (Correct Answer)
Abdominal and Pelvic Radiology Explanation: ***Urgent decompressive laparotomy***
- The definitive treatment for abdominal compartment syndrome (ACS) is **urgent surgical decompression** via **decompressive laparotomy**.
- This involves opening the abdominal fascia to immediately **reduce intra-abdominal pressure (IAP)**, typically indicated when IAP >20 mmHg with new organ dysfunction.
- Decompression is crucial to prevent irreversible organ damage, restore perfusion to compressed organs, and improve ventilation.
- The abdomen is often left open temporarily with negative pressure wound therapy until the patient stabilizes.
*Antihypertensives*
- Antihypertensives may manage systemic hypertension but do not address the **elevated intra-abdominal pressure** that is the primary pathology in ACS.
- This approach is insufficient and could worsen **organ perfusion** by reducing the perfusion pressure gradient (MAP - IAP) to already compressed abdominal organs.
- ACS requires mechanical decompression, not pharmacological blood pressure management.
*Urgent Fasciotomy*
- Fasciotomy is the correct treatment for **extremity compartment syndrome** (e.g., leg, forearm), where it relieves pressure within muscle compartments.
- It is anatomically inappropriate for **abdominal compartment syndrome**, which requires opening the abdominal cavity, not limb fascial compartments.
- This represents a fundamental misunderstanding of the anatomical site requiring decompression.
*Wait and monitor for 24 hours*
- ACS is a **surgical emergency** that can rapidly progress to multiorgan failure, acute kidney injury, respiratory failure, and cardiovascular collapse.
- Delaying intervention by 24 hours would likely result in **irreversible organ damage** and significantly increased mortality.
- Once diagnosed (IAP >20 mmHg with organ dysfunction), urgent decompression is mandatory.
