(image) Picture of selective renal arteriogram for accessory renal artery to lower pole, how we used the contrast:

  • A- 1-3 ml at 1 ml / second. (true)
  • B- 5-10ml at 2-3ml / second.
Unfortunately, I don't have access to images, so I can't directly analyze the picture of the selective renal arteriogram for the accessory renal artery to the lower pole. However, based on the information you provided, I can offer some insights into the contrast used:

1. Option A (1-3 ml at 1 ml/second) is more likely to be accurate in this scenario.

Here's why:

- Selective renal arteriogram:

This procedure focuses on visualizing a specific artery, usually the renal artery supplying a particular portion of the kidney. Using a smaller volume of contrast (1-3 ml) is common in selective procedures compared to non-selective angiography where larger volumes are used to visualize the entire arterial system.

- Lower pole:

Supplying the lower pole of the kidney typically requires a smaller amount of contrast compared to the upper or middle poles due to the generally smaller size of the lower pole vasculature.

- Injection rate:

1 ml/second is an appropriate injection rate for selective renal angiography. Faster injection rates can lead to artifacts or miss visualization of smaller vessels.

Therefore, using 1-3 ml of contrast at a rate of 1 ml/second aligns well with the principles of selective renal angiography for the lower pole.

2. Option B (5-10 ml at 2-3 ml/second) is less likely to be suitable for this scenario.

While not completely impossible, using 5-10 ml of contrast at a faster rate (2-3 ml/second) for a selective lower pole arteriogram is less common for several reasons:

- Higher risk of contrast overload:

Increased contrast volume and faster injection rate can increase the risk of nephrotoxicity (kidney damage) and other complications.

- Potential for obscuring detail:

Injecting a larger volume too quickly can make it harder to visualize the smaller vessels of the lower pole due to the rapid flow and dilution of the contrast.

However, it's important to note that the optimal contrast volume and injection rate can vary depending on several factors like the specific anatomy of the patient, the size of the accessory artery, and the technical considerations of the equipment used.

Ultimately, the best way to determine the exact contrast used in your image is to consult with the radiologist or physician who performed the procedure. They can provide specific details based on the individual case and angiographic findings.
