Roughly 1 in 3 international patients who contact Chinese hospitals arrives with imaging that cannot be used. The files are too compressed, the report is missing, or the scan was taken on equipment the receiving radiologist cannot properly calibrate against. That single failure point wastes weeks. For anyone searching for guidance on Imaging Assessment in Shanghai: What to Send, the answer is narrower and more technical than most people assume — and getting it right is the difference between a useful second opinion and a polite rejection email.

Shanghai concentrates an unusual amount of diagnostic firepower. Eighteen of China’s Fudan Top 100 hospitals sit in the city, behind only Beijing’s 21. Facilities like Zhongshan Hospital Fudan University and Ruijin Hospital run imaging volumes that most Western centers would find difficult to match, which means their radiologists see rare presentations far more often. But volume cuts both ways. These departments are busy, and they triage incoming foreign cases by how clean the submitted material is.

The Problem: Your Scans Are Probably Unusable as Sent

A 2023 survey published in the Journal of the American College of Radiology found that roughly 40% of external imaging submitted for second opinions was inadequate for diagnostic interpretation — missing series, wrong windowing, or incomplete coverage of the region of interest. That figure describes domestic US transfers. Cross-border submissions are worse.

Here is what typically happens. A patient in Dubai or Toronto gets an MRI, photographs the printed film on a lightbox with a phone, and emails the JPEG. The Chinese radiologist opens it, sees a 2-megapixel image of a 12-megapixel dataset, and cannot measure anything. No lesion dimensions. No Hounsfield units on the CT. Nothing to compare against a prior study.

The patient waits two weeks for a reply that says “please resend.” And the clock on their condition keeps running.

There is a second problem that has nothing to do with file quality. Public hospital general outpatient departments in China do not accept advance bookings from overseas. You queue for a same-day number, and surgery can only be scheduled after an in-person consultation. That rule is not negotiable, and it catches international patients off guard constantly. The workaround — and it is a legitimate one — is the hospital’s international or VIP department, where a senior specialist reviews your materials in advance. Expect to pay roughly 1.5 to 2 times the standard channel rate for that access.

What Chinese Radiology Departments Actually Need From You

Forget the marketing language about “comprehensive records.” The technical requirement is specific.

Original DICOM files, not exports

DICOM is the raw imaging format. Every modern scanner produces it, and every hospital can read it. Ask your imaging center for the full study on a CD, DVD, or secure download link — including all series, not just the ones the technician thought looked interesting. A chest CT might contain six or seven series. Send all of them.

Compressed formats lose diagnostic data permanently. A JPEG cannot be windowed, measured, or reconstructed. If your only copy is a PDF of the report, you have a summary, not an imaging assessment.

The written radiology report

This matters more than patients realize. The Chinese specialist needs to know what your local radiologist measured, what contrast protocol was used, and what the clinical question was. A report in English is fine — most international departments at Shanghai’s top hospitals work in English daily. If your report is in Arabic, Russian, or Spanish, arrange a certified translation.

A one-page clinical summary

Not your entire history. One page: presenting symptoms, date of onset, prior treatments, current medications, and the specific question you want answered. “Is this lesion malignant?” is a good question. “What do you think?” is not.

How the Remote Review Process Actually Runs

Most patients assume the sequence is: send scans, get an answer, book a flight. The real sequence has more steps, and understanding them prevents expensive mistakes.

Step one — records intake. You submit DICOM files and reports through a secure transfer. Our team checks completeness before anything goes to a physician. Roughly a quarter of submissions need a follow-up request at this stage.

Step two — translation and formatting. Chinese hospital systems expect a structured case file. Reports get translated where needed and organized so the reviewing specialist is not hunting for the relevant series.

Step three — the actual review. This is where the choice matters. A written second opinion from a top-hospital specialist runs $300–500 and returns a documented analysis with treatment direction. A video consultation with the specialty team runs $100–300 at a standard international department, or $500–800 with a top specialist, and lets you ask questions directly. For complex cases involving multiple organ systems, a multidisciplinary team review runs $1,500–2,000.

Step four — a decision point. Based on that review, you either have a plan worth traveling for, or you do not. That is the entire purpose of the exercise. Finding out remotely that surgery is not indicated saves you a $4,000 trip.
