**Core Concept**
In the evaluation of suspected ovarian cancer, imaging plays a crucial role in assessing the extent of disease and guiding treatment decisions. The imaging workup typically includes a combination of ultrasound, computed tomography (CT), and magnetic resonance imaging (MRI) to evaluate the ovaries, uterus, and surrounding structures.

**Why the Correct Answer is Right**
The correct imaging studies are chosen based on the clinical scenario and the suspected extent of disease. In suspected ovarian cancer, a thorough evaluation of the pelvic and abdominal cavities is essential. Ultrasound is often the first-line imaging modality due to its high sensitivity and specificity for detecting ovarian lesions. CT scans are useful for assessing the extent of disease and identifying any metastases to lymph nodes or distant organs. MRI can provide additional information on the relationship between the tumor and surrounding structures. However, in cases of suspected ovarian cancer, a chest X-ray or a bone scan is not typically required as an initial imaging study.

**Why Each Wrong Option is Incorrect**
**Option A:** Ultrasound is an essential imaging modality in suspected ovarian cancer, making it an incorrect choice for the exception.
**Option B:** CT scans are also a crucial part of the imaging workup, as they provide valuable information on the extent of disease and identify any metastases.
**Option C:** MRI can be useful in specific cases, such as when the relationship between the tumor and surrounding structures needs to be evaluated, but it is not typically required as an initial imaging study in all cases of suspected ovarian cancer.

**Clinical Pearl / High-Yield Fact**
In cases of suspected ovarian cancer, it is essential to remember that imaging studies should be tailored to the individual patient's clinical scenario and the suspected extent of disease.

**Correct Answer:** D.
